TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
|
|
||||||
|
|
||||||
1. Definitions.
|
|
||||||
|
|
||||||
"License" shall mean the terms and conditions for use, reproduction,
|
|
||||||
and distribution as defined by Sections 1 through 9 of this document.
|
|
||||||
|
|
||||||
"Licensor" shall mean the copyright owner or entity authorized by
|
|
||||||
the copyright owner that is granting the License.
|
|
||||||
|
|
||||||
"Legal Entity" shall mean the union of the acting entity and all
|
|
||||||
other entities that control, are controlled by, or are under common
|
|
||||||
control with that entity. For the purposes of this definition,
|
|
||||||
"control" means (i) the power, direct or indirect, to cause the
|
|
||||||
direction or management of such entity, whether by contract or
|
|
||||||
otherwise, or (ii) ownership of fifty percent (50%) or more of the
|
|
||||||
outstanding shares, or (iii) beneficial ownership of such entity.
|
|
||||||
|
|
||||||
"You" (or "Your") shall mean an individual or Legal Entity
|
|
||||||
exercising permissions granted by this License.
|
|
||||||
|
|
||||||
"Source" form shall mean the preferred form for making modifications,
|
|
||||||
including but not limited to software source code, documentation
|
|
||||||
source, and configuration files.
|
|
||||||
|
|
||||||
"Object" form shall mean any form resulting from mechanical
|
|
||||||
transformation or translation of a Source form, including but
|
|
||||||
not limited to compiled object code, generated documentation,
|
|
||||||
and conversions to other media types.
|
|
||||||
|
|
||||||
"Work" shall mean the work of authorship, whether in Source or
|
|
||||||
Object form, made available under the License, as indicated by a
|
|
||||||
copyright notice that is included in or attached to the work
|
|
||||||
(an example is provided in the Appendix below).
|
|
||||||
|
|
||||||
"Derivative Works" shall mean any work, whether in Source or Object
|
|
||||||
form, that is based on (or derived from) the Work and for which the
|
|
||||||
editorial revisions, annotations, elaborations, or other modifications
|
|
||||||
represent, as a whole, an original work of authorship. For the purposes
|
|
||||||
of this License, Derivative Works shall not include works that remain
|
|
||||||
separable from, or merely link (or bind by name) to the interfaces of,
|
|
||||||
the Work and Derivative Works thereof.
|
|
||||||
|
|
||||||
"Contribution" shall mean any work of authorship, including
|
|
||||||
the original version of the Work and any modifications or additions
|
|
||||||
to that Work or Derivative Works thereof, that is intentionally
|
|
||||||
submitted to Licensor for inclusion in the Work by the copyright owner
|
|
||||||
or by an individual or Legal Entity authorized to submit on behalf of
|
|
||||||
the copyright owner. For the purposes of this definition, "submitted"
|
|
||||||
means any form of electronic, verbal, or written communication sent
|
|
||||||
to the Licensor or its representatives, including but not limited to
|
|
||||||
communication on electronic mailing lists, source code control systems,
|
|
||||||
and issue tracking systems that are managed by, or on behalf of, the
|
|
||||||
Licensor for the purpose of discussing and improving the Work, but
|
|
||||||
excluding communication that is conspicuously marked or otherwise
|
|
||||||
designated in writing by the copyright owner as "Not a Contribution."
|
|
||||||
|
|
||||||
"Contributor" shall mean Licensor and any individual or Legal Entity
|
|
||||||
on behalf of whom a Contribution has been received by Licensor and
|
|
||||||
subsequently incorporated within the Work.
|
|
||||||
|
|
||||||
2. Grant of Copyright License. Subject to the terms and conditions of
|
|
||||||
this License, each Contributor hereby grants to You a perpetual,
|
|
||||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
|
||||||
copyright license to reproduce, prepare Derivative Works of,
|
|
||||||
publicly display, publicly perform, sublicense, and distribute the
|
|
||||||
Work and such Derivative Works in Source or Object form.
|
|
||||||
|
|
||||||
3. Grant of Patent License. Subject to the terms and conditions of
|
|
||||||
this License, each Contributor hereby grants to You a perpetual,
|
|
||||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
|
||||||
(except as stated in this section) patent license to make, have made,
|
|
||||||
use, offer to sell, sell, import, and otherwise transfer the Work,
|
|
||||||
where such license applies only to those patent claims licensable
|
|
||||||
by such Contributor that are necessarily infringed by their
|
|
||||||
Contribution(s) alone or by combination of their Contribution(s)
|
|
||||||
with the Work to which such Contribution(s) was submitted. If You
|
|
||||||
institute patent litigation against any entity (including a
|
|
||||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
|
||||||
or a Contribution incorporated within the Work constitutes direct
|
|
||||||
or contributory patent infringement, then any patent licenses
|
|
||||||
granted to You under this License for that Work shall terminate
|
|
||||||
as of the date such litigation is filed.
|
|
||||||
|
|
||||||
4. Redistribution. You may reproduce and distribute copies of the
|
|
||||||
Work or Derivative Works thereof in any medium, with or without
|
|
||||||
modifications, and in Source or Object form, provided that You
|
|
||||||
meet the following conditions:
|
|
||||||
|
|
||||||
(a) You must give any other recipients of the Work or
|
|
||||||
Derivative Works a copy of this License; and
|
|
||||||
|
|
||||||
(b) You must cause any modified files to carry prominent notices
|
|
||||||
stating that You changed the files; and
|
|
||||||
|
|
||||||
(c) You must retain, in the Source form of any Derivative Works
|
|
||||||
that You distribute, all copyright, patent, trademark, and
|
|
||||||
attribution notices from the Source form of the Work,
|
|
||||||
excluding those notices that do not pertain to any part of
|
|
||||||
the Derivative Works; and
|
|
||||||
|
|
||||||
(d) If the Work includes a "NOTICE" text file as part of its
|
|
||||||
distribution, then any Derivative Works that You distribute must
|
|
||||||
include a readable copy of the attribution notices contained
|
|
||||||
within such NOTICE file, excluding those notices that do not
|
|
||||||
pertain to any part of the Derivative Works, in at least one
|
|
||||||
of the following places: within a NOTICE text file distributed
|
|
||||||
as part of the Derivative Works; within the Source form or
|
|
||||||
documentation, if provided along with the Derivative Works; or,
|
|
||||||
within a display generated by the Derivative Works, if and
|
|
||||||
wherever such third-party notices normally appear. The contents
|
|
||||||
of the NOTICE file are for informational purposes only and
|
|
||||||
do not modify the License. You may add Your own attribution
|
|
||||||
notices within Derivative Works that You distribute, alongside
|
|
||||||
or as an addendum to the NOTICE text from the Work, provided
|
|
||||||
that such additional attribution notices cannot be construed
|
|
||||||
as modifying the License.
|
|
||||||
|
|
||||||
You may add Your own copyright statement to Your modifications and
|
|
||||||
may provide additional or different license terms and conditions
|
|
||||||
for use, reproduction, or distribution of Your modifications, or
|
|
||||||
for any such Derivative Works as a whole, provided Your use,
|
|
||||||
reproduction, and distribution of the Work otherwise complies with
|
|
||||||
the conditions stated in this License.
|
|
||||||
|
|
||||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
|
||||||
any Contribution intentionally submitted for inclusion in the Work
|
|
||||||
by You to the Licensor shall be under the terms and conditions of
|
|
||||||
this License, without any additional terms or conditions.
|
|
||||||
Notwithstanding the above, nothing herein shall supersede or modify
|
|
||||||
the terms of any separate license agreement you may have executed
|
|
||||||
with Licensor regarding such Contributions.
|
|
||||||
|
|
||||||
6. Trademarks. This License does not grant permission to use the trade
|
|
||||||
names, trademarks, service marks, or product names of the Licensor,
|
|
||||||
except as required for reasonable and customary use in describing the
|
|
||||||
origin of the Work and reproducing the content of the NOTICE file.
|
|
||||||
|
|
||||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
|
||||||
agreed to in writing, Licensor provides the Work (and each
|
|
||||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
|
||||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
|
||||||
implied, including, without limitation, any warranties or conditions
|
|
||||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
|
||||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
|
||||||
appropriateness of using or redistributing the Work and assume any
|
|
||||||
risks associated with Your exercise of permissions under this License.
|
|
||||||
|
|
||||||
8. Limitation of Liability. In no event and under no legal theory,
|
|
||||||
whether in tort (including negligence), contract, or otherwise,
|
|
||||||
unless required by applicable law (such as deliberate and grossly
|
|
||||||
negligent acts) or agreed to in writing, shall any Contributor be
|
|
||||||
liable to You for damages, including any direct, indirect, special,
|
|
||||||
incidental, or consequential damages of any character arising as a
|
|
||||||
result of this License or out of the use or inability to use the
|
|
||||||
Work (including but not limited to damages for loss of goodwill,
|
|
||||||
work stoppage, computer failure or malfunction, or any and all
|
|
||||||
other commercial damages or losses), even if such Contributor
|
|
||||||
has been advised of the possibility of such damages.
|
|
||||||
|
|
||||||
9. Accepting Warranty or Additional Liability. While redistributing
|
|
||||||
the Work or Derivative Works thereof, You may choose to offer,
|
|
||||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
|
||||||
or other liability obligations and/or rights consistent with this
|
|
||||||
License. However, in accepting such obligations, You may act only
|
|
||||||
on Your own behalf and on Your sole responsibility, not on behalf
|
|
||||||
of any other Contributor, and only if You agree to indemnify,
|
|
||||||
defend, and hold each Contributor harmless for any liability
|
|
||||||
incurred by, or claims asserted against, such Contributor by reason
|
|
||||||
of your accepting any such warranty or additional liability.
|
|
||||||
|
|
||||||
END OF TERMS AND CONDITIONS

|
||||||
|
|
||||||
APPENDIX: How to apply the Apache License to your work.
|

|
||||||
"Contribution" shall mean any work of authorship, including
|
|
||||||
the original version of the Work and any modifications or additions
|
|
||||||
to that Work or Derivative Works thereof, that is intentionally
|
|
||||||
submitted to Licensor for inclusion in the Work by the copyright owner
|
|
||||||
or by an individual or Legal Entity authorized to submit on behalf of
|
|
||||||
the copyright owner. For the purposes of this definition, "submitted"
|
|
||||||
means any form of electronic, verbal, or written communication sent
|
|
||||||
to the Licensor or its representatives, including but not limited to
|
|
||||||
communication on electronic mailing lists, source code control systems,
|
|
||||||
and issue tracking systems that are managed by, or on behalf of, the
|
|
||||||
Licensor for the purpose of discussing and improving the Work, but
|
|
||||||
excluding communication that is conspicuously marked or otherwise
|
|
||||||
designated in writing by the copyright owner as "Not a Contribution."
|
|
||||||
|
|
||||||
"Contributor" shall mean Licensor and any individual or Legal Entity
|
|
||||||
on behalf of whom a Contribution has been received by Licensor and
|
|
||||||
subsequently incorporated within the Work.
|
|
||||||
|
|
||||||
2. Grant of Copyright License. Subject to the terms and conditions of
|
|
||||||
this License, each Contributor hereby grants to You a perpetual,
|
|
||||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
|
||||||
copyright license to reproduce, prepare Derivative Works of,
|
|
||||||
publicly display, publicly perform, sublicense, and distribute the
|
|
||||||
Work and such Derivative Works in Source or Object form.
|
|
||||||
|
|
||||||
3. Grant of Patent License. Subject to the terms and conditions of
|
|
||||||
this License, each Contributor hereby grants to You a perpetual,
|
|
||||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
|
||||||
(except as stated in this section) patent license to make, have made,
|
|
||||||
use, offer to sell, sell, import, and otherwise transfer the Work,
|
|
||||||
where such license applies only to those patent claims licensable
|
|
||||||
by such Contributor that are necessarily infringed by their
|
|
||||||
Contribution(s) alone or by combination of their Contribution(s)
|
|
||||||
with the Work to which such Contribution(s) was submitted. If You
|
|
||||||
institute patent litigation against any entity (including a
|
|
||||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
|
||||||
or a Contribution incorporated within the Work constitutes direct
|
|
||||||
or contributory patent infringement, then any patent licenses
|
|
||||||
granted to You under this License for that Work shall terminate
|
|
||||||
as of the date such litigation is filed.
|
|
||||||
|
|
||||||
4. Redistribution. You may reproduce and distribute copies of the
|
|
||||||
Work or Derivative Works thereof in any medium, with or without
|
|
||||||
modifications, and in Source or Object form, provided that You
|
|
||||||
meet the following conditions:
|
|
||||||
|
|
||||||
(a) You must give any other recipients of the Work or
|
|
||||||
Derivative Works a copy of this License; and
|
|
||||||
|
|
||||||
(b) You must cause any modified files to carry prominent notices
|
|
||||||
stating that You changed the files; and
|
|
||||||
|
|
||||||
(c) You must retain, in the Source form of any Derivative Works
|
|
||||||
that You distribute, all copyright, patent, trademark, and
|
|
||||||
attribution notices from the Source form of the Work,
|
|
||||||
excluding those notices that do not pertain to any part of
|
|
||||||
the Derivative Works; and
|
|
||||||
|
|
||||||
(d) If the Work includes a "NOTICE" text file as part of its
|
|
||||||
distribution, then any Derivative Works that You distribute must
|
|
||||||
include a readable copy of the attribution notices contained
|
|
||||||
within such NOTICE file, excluding those notices that do not
|
|
||||||
pertain to any part of the Derivative Works, in at least one
|
|
||||||
of the following places: within a NOTICE text file distributed
|
|
||||||
as part of the Derivative Works; within the Source form or
|
|
||||||
documentation, if provided along with the Derivative Works; or,
|
|
||||||
within a display generated by the Derivative Works, if and
|
|
||||||
wherever such third-party notices normally appear. The contents
|
|
||||||
of the NOTICE file are for informational purposes only and
|
|
||||||
do not modify the License. You may add Your own attribution
|
|
||||||
notices within Derivative Works that You distribute, alongside
|
|
||||||
or as an addendum to the NOTICE text from the Work, provided
|
|
||||||
that such additional attribution notices cannot be construed
|
|
||||||
as modifying the License.
|
|
||||||
|
|
||||||
You may add Your own copyright statement to Your modifications and
|
|
||||||
may provide additional or different license terms and conditions
|
|
||||||
for use, reproduction, or distribution of Your modifications, or
|
|
||||||
for any such Derivative Works as a whole, provided Your use,
|
|
||||||
reproduction, and distribution of the Work otherwise complies with
|
|
||||||
the conditions stated in this License.
|
|
||||||
|
|
||||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
|
||||||
any Contribution intentionally submitted for inclusion in the Work
|
|
||||||
by You to the Licensor shall be under the terms and conditions of
|
|
||||||
this License, without any additional terms or conditions.
|
|
||||||
Notwithstanding the above, nothing herein shall supersede or modify
|
|
||||||
the terms of any separate license agreement you may have executed
|
|
||||||
with Licensor regarding such Contributions.
|
|
||||||
|
|
||||||
6. Trademarks. This License does not grant permission to use the trade
|
|
||||||
names, trademarks, service marks, or product names of the Licensor,
|
|
||||||
except as required for reasonable and customary use in describing the
|
|
||||||
origin of the Work and reproducing the content of the NOTICE file.
|
|
||||||
|
|
||||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
|
||||||
agreed to in writing, Licensor provides the Work (and each
|
|
||||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
|
||||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
|
||||||
implied, including, without limitation, any warranties or conditions
|
|
||||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
|
||||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
|
||||||
appropriateness of using or redistributing the Work and assume any
|
|
||||||
risks associated with Your exercise of permissions under this License.
|
|
||||||
|
|
||||||
8. Limitation of Liability. In no event and under no legal theory,
|
|
||||||
whether in tort (including negligence), contract, or otherwise,
|
|
||||||
unless required by applicable law (such as deliberate and grossly
|
|
||||||
negligent acts) or agreed to in writing, shall any Contributor be
|
|
||||||
liable to You for damages, including any direct, indirect, special,
|
|
||||||
incidental, or consequential damages of any character arising as a
|
|
||||||
result of this License or out of the use or inability to use the
|
|
||||||
Work (including but not limited to damages for loss of goodwill,
|
|
||||||
work stoppage, computer failure or malfunction, or any and all
|
|
||||||
other commercial damages or losses), even if such Contributor
|
|
||||||
has been advised of the possibility of such damages.
|
|
||||||
|
|
||||||
9. Accepting Warranty or Additional Liability. While redistributing
|
|
||||||
the Work or Derivative Works thereof, You may choose to offer,
|
|
||||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
|
||||||
or other liability obligations and/or rights consistent with this
|
|
||||||
License. However, in accepting such obligations, You may act only
|
|
||||||
on Your own behalf and on Your sole responsibility, not on behalf
|
|
||||||
of any other Contributor, and only if You agree to indemnify,
|
|
||||||
defend, and hold each Contributor harmless for any liability
|
|
||||||
incurred by, or claims asserted against, such Contributor by reason
|
|
||||||
of your accepting any such warranty or additional liability.

||||||

//! Additional methods for Read and Write
|
|
||||||
//!
|
|
||||||
//! The additional methods implemented allow reading and writing integers and floats
|
|
||||||
//! in the specified endianness.
|
|
||||||
//!
|
|
||||||
//! # Usage
|
|
||||||
//!
|
|
||||||
//! Basically, you need to `use` the trait WritePodExt or ReadPodExt.
|
|
||||||
//!
|
|
||||||
//! # Examples
|
|
||||||
//!
|
|
||||||
//! ## Reading
|
|
||||||
//!
|
|
||||||
//! To read some value from a reader, import ReadPodExt and the needed endianness.
|
|
||||||
//!
|
|
||||||
//! ```
|
|
||||||
//! use podio::{ReadPodExt, BigEndian};
|
|
||||||
//!
|
|
||||||
//! let slice: &[u8] = &[0x10, 0x20, 0x30, 0x40];
|
|
||||||
//! let mut reader = std::io::Cursor::new(slice);
|
|
||||||
//!
|
|
||||||
//! let value = reader.read_u32::<BigEndian>().unwrap();
|
|
||||||
//!
|
|
||||||
//! assert_eq!(value, 0x10203040);
|
|
||||||
//! ```
|
|
||||||
//!
|
|
||||||
//! ## Writing
|
|
||||||
//!
|
|
||||||
//! For writing, you need to import the trait WritePodExt.
|
|
||||||
//!
|
|
||||||
//! ```
|
|
||||||
//! use podio::{WritePodExt, LittleEndian};
|
|
||||||
//!
|
|
||||||
//! let slice: &mut [u8] = &mut [0; 2];
|
|
||||||
//! let mut writer = std::io::Cursor::new(slice);
|
|
||||||
//!
|
|
||||||
//! writer.write_u16::<LittleEndian>(0x8802).unwrap();
|
|
||||||
//!
|
|
||||||
//! assert_eq!(writer.into_inner(), &[0x02, 0x88]);
|
|
||||||
//! ```
|
|
||||||
//!
|
|
||||||
//! ## Read exact
|
|
||||||
//!
|
|
||||||
//! One additional method, not really dealing with POD, is `read_exact`.
|
|
||||||
//!
|
|
||||||
//! ```
|
|
||||||
//! use podio::ReadPodExt;
|
|
||||||
//!
|
|
||||||
//! let slice: &[u8] = &[0, 1, 2, 3];
|
|
||||||
//! let mut reader = std::io::Cursor::new(slice);
|
|
||||||
//!
|
|
||||||
//! assert_eq!(reader.read_exact(1).unwrap(), [0]);
|
|
||||||
//! assert_eq!(reader.read_exact(2).unwrap(), [1,2]);
|
|
||||||
//! assert_eq!(reader.read_exact(0).unwrap(), []);
|
|
||||||
//! assert_eq!(reader.read_exact(1).unwrap(), [3]);
|
|
||||||
//! assert!(reader.read_exact(1).is_err());

# Contributor Covenant Code of Conduct
|
||||||
|
|
||||||
|
## Our Pledge
|
||||||
|
|
||||||
|
In the interest of fostering an open and welcoming environment, we as
|
||||||
|
contributors and maintainers pledge to make participation in our project and
|
||||||
|
our community a harassment-free experience for everyone, regardless of age, body
|
||||||
|
size, disability, ethnicity, sex characteristics, gender identity and expression,
|
||||||
|
level of experience, education, socio-economic status, nationality, personal
|
||||||
|
appearance, race, religion, or sexual identity and orientation.
|
||||||
|
|
||||||
|
## Our Standards
|
||||||
|
|
||||||
|
Examples of behavior that contributes to creating a positive environment
|
||||||
|
include:
|
||||||
|
|
||||||
|
* Using welcoming and inclusive language
|
||||||
|
* Being respectful of differing viewpoints and experiences
|
||||||
|
* Gracefully accepting constructive criticism
|
||||||
|
* Focusing on what is best for the community
|
||||||
|
* Showing empathy towards other community members
|
||||||
|
|
||||||
|
Examples of unacceptable behavior by participants include:
|
||||||
|
|
||||||
|
* The use of sexualized language or imagery and unwelcome sexual attention or
|
||||||
|
advances
|
||||||
|
* Trolling, insulting/derogatory comments, and personal or political attacks
|
||||||
|
* Public or private harassment
|
||||||
|
* Publishing others' private information, such as a physical or electronic
|
||||||
|
address, without explicit permission
|
||||||
|
* Other conduct which could reasonably be considered inappropriate in a
|
||||||
|
professional setting
|
||||||
|
|
||||||
|
## Our Responsibilities
|
||||||
|
|
||||||
|
Project maintainers are responsible for clarifying the standards of acceptable
|
||||||
|
behavior and are expected to take appropriate and fair corrective action in
|
||||||
|
response to any instances of unacceptable behavior.
|
||||||
|
|
||||||
|
Project maintainers have the right and responsibility to remove, edit, or
|
||||||
|
reject comments, commits, code, wiki edits, issues, and other contributions
|
||||||
|
that are not aligned to this Code of Conduct, or to ban temporarily or
|
||||||
|
permanently any contributor for other behaviors that they deem inappropriate,
|
||||||
|
threatening, offensive, or harmful.
|
||||||
|
|
||||||
|
## Scope
|
||||||
|
|
||||||
|
This Code of Conduct applies within all project spaces, and it also applies when
|
||||||
|
an individual is representing the project or its community in public spaces.
|
||||||
|
Examples of representing a project or community include using an official
|
||||||
|
project e-mail address, posting via an official social media account, or acting
|
||||||
|
as an appointed representative at an online or offline event. Representation of
|
||||||
|
a project may be further defined and clarified by project maintainers.
|
||||||
|
|
||||||
|
## Enforcement
|
||||||
|
|
||||||

```
|
```
|
||||||
|
|
||||||
You can further control the backend of `deflate` compression method with these features:
|
The features available are:
|
||||||
* `deflate` (enabled by default) uses [miniz_oxide](https://github.com/Frommi/miniz_oxide)
|
|
||||||
* `deflate-miniz` uses [miniz](https://github.com/richgel999/miniz)
|
|
||||||
* `deflate-zlib` uses zlib
|
|
||||||
|
|
||||||
For example:
|
* `aes-crypto`: Enables decryption of files which were encrypted with AES. Supports AE-1 and AE-2 methods.
|
||||||
|
* `deflate`: Enables the deflate compression algorithm, which is the default for zip files.
|
||||||
|
* `bzip2`: Enables the BZip2 compression algorithm.
|
||||||
|
* `time`: Enables features using the [time](https://github.com/rust-lang-deprecated/time) crate.
|
||||||
|
* `zstd`: Enables the Zstandard compression algorithm.
|
||||||
|
|
||||||
```toml
|
All of these are enabled by default.

MSRV
|

```
|
----
|
||||||
|
|
||||||
|
Our current Minimum Supported Rust Version is **1.54.0**. When adding features,
|
||||||
|
we will follow these guidelines:
|
||||||
|
|
||||||
|
- We will always support the latest four minor Rust versions. This gives you a 6
|
||||||
|
month window to upgrade your compiler.
|
||||||
|
- Any change to the MSRV will be accompanied with a **minor** version bump
|
||||||
|
- While the crate is pre-1.0, this will be a change to the PATCH version.

//! A basic ZipReader/Writer crate
|
//! A library for reading and writing ZIP archives.
|
||||||
|
//! ZIP is a format designed for cross-platform file "archiving".
|
||||||
|
//! That is, storing a collection of files in a single datastream
|
||||||
|
//! to make them easier to share between computers.
|
||||||
|
//! Additionally, ZIP is able to compress and encrypt files in its
|
||||||
|
//! archives.
|
||||||
|
//!
|
||||||
|
//! The current implementation is based on [PKWARE's APPNOTE.TXT v6.3.9](https://pkware.cachefly.net/webdocs/casestudies/APPNOTE.TXT)
|
||||||
|
//!
|
||||||
|
//! ---
|
||||||
|
//!
|
||||||
|
//! [`zip`](`crate`) has support for the most common ZIP archives found in common use.
|
||||||
|
//! However, in special cases,
|
||||||
|
//! there are some zip archives that are difficult to read or write.
|
||||||
|
//!
