|
||||
** Removed depricated rustc-serialize support
|
||||
Rustc-serialize was a stopgap until projects like Serde were able to catch up.
|
||||
With macros stabilization on its way, we are able to switch to serde without any
|
||||
big user-friendliness issues. Major congratulations to Serde for coming this far!
|
||||
|
||||
** Moved Refbox, Strbox and Slicebox into a "refbox" module
|
||||
Refbox, Strbox and Slicebox are still an integral piece of bincode, but since
|
||||
they are mainly used by power-users, this move will make the crate API more organized
|
||||
and easier for new users to understand.
|
||||
|
||||
** Upgraded to Serde 0.9.*
|
||||
Serde 0.9.* gives us a better API surface area and allows use of procedural macros for
|
||||
deriving serialize and deserialize implemenetations.
|
||||
|
||||
** Moved serde functions into global module
|
||||
Since serde is the only supported serialization mechanism, it makes sense to have these
|
||||
functions available at the top level.
|
||||
|
||||
** Added the ability to chose your own endian encoding.
|
||||
This functionality is located in the endian_choice module.
|
||||
|
||||
** Changed SizeLimit to be a trait instead of an enum
|
||||
Mostly for performance reasons.
|
||||
|
||||
** Removed RefBox / StrBox / SliceBox
|
||||
Since rustc-serialize support was phased out, you can use `Cow<T>` with serde.

|
||||
A compact encoder / decoder pair that uses an binary zero-fluff encoding scheme.
|
||||
The size of the encoded object will be the same or smaller than the size that
|
||||
the object takes up in memory in a running Rust program.
|
||||
|
||||
In addition to exposing two simple funcitons that encode to Vec<u8> and decode
|
||||
from Vec<u8>, binary-encode exposes a Reader/Writer API that makes it work
|
||||
perfectly with other stream-based apis such as rust files, network streams,
|
||||
and the [flate2-rs](https://github.com/alexcrichton/flate2-rs) compression
|
||||
library.
|
||||
|
||||
[Api Documentation](http://tyoverby.github.io/bincode/bincode/)
|
||||
|
||||
## Example
|
||||
|
||||
^code(./examples/basic.rs)
|
||||
|
||||
|
||||
## Details
|
||||
|
||||
The encoding (and thus decoding) proceeds unsurprisingly -- primitive
|
||||
types are encoded according to the underlying `Writer`, tuples and
|
||||
structs are encoded by encoding their fields one-by-one, and enums are
|
||||
encoded by first writing out the tag representing the variant and
|
||||
then the contents.
|
||||
|
||||
However, there are some implementation details to be aware of:
|
||||
|
||||
* `isize`/`usize` are encoded as `i64`/`u64`, for portability.
|
||||
* enums variants are encoded as a `u32` instead that as a `uint`.
|
||||
`u32` is enough for all practical uses.
|
||||
* `str` is encoded as `(u64, &[u8])`, where the `u64` is the number of
|
||||
bytes contained in the encoded string.

//!
|
||||
//! The default endianness is little.
|
||||
//! Bincode is a crate for encoding and decoding using a tiny binary
|
||||
//! serialization strategy. Using it, you can easily go from having
|
||||
//! an object in memory, quickly serialize it to bytes, and then
|
||||
//! deserialize it back just as fast!
|
||||
//!
|
||||
//! ### Using Basic Functions
|
||||
//!
|
||||
//! ```rust
|
||||
//! extern crate bincode;
|
||||
//! use bincode::{serialize, deserialize, Bounded};
|
||||
//! use bincode::{serialize, deserialize};
|
||||
//! fn main() {
|
||||
//! // The object that we will serialize.
|
||||
//! let target = Some("hello world".to_string());
|
||||
//! // The maximum size of the encoded message.
|
||||
//! let limit = Bounded(20);
|
||||
//! let target: Option<String> = Some("hello world".to_string());
|
||||
//!
|
||||
//! let encoded: Vec<u8> = serialize(&target, limit).unwrap();
|
||||
//! let encoded: Vec<u8> = serialize(&target).unwrap();
|
||||
//! let decoded: Option<String> = deserialize(&encoded[..]).unwrap();
|
||||
//! assert_eq!(target, decoded);
|
||||
//! }
