Project changelog - -/// Release 0.4.3 (2017-12-07) -/// -/// * Bump lazy-static dependency to `^1.0` -/// * `cargo test --release` now works when testing libloading. -pub mod r0_4_3 {} - - -/// Release 0.4.2 (2017-09-24) -/// -/// * Improved error and race-condition handling on Windows; -/// * Improved documentation about thread-safety of Library; -/// * Added `Symbol::::lift_option() -> Option>` convenience method. -pub mod r0_4_2 {} - - -/// Release 0.4.1 (2017-08-29) -/// -/// * Solaris support -pub mod r0_4_1 {} - -/// Release 0.4.0 (2017-05-01) -/// -/// * Remove build-time dependency on target_build_utils (and by extension serde/phf); -/// * Require at least version 1.14.0 of rustc to build; -/// * Actually, it is cargo which has to be more recent here. The one shipped with rustc 1.14.0 -/// is what’s being required from now on. -pub mod r0_4_0 {} - -/// Release 0.3.4 (2017-03-25) -/// -/// * Remove rogue println! -pub mod r0_3_4 {} - -/// Release 0.3.3 (2017-03-25) -/// -/// * Panics when `Library::get` is called for incompatibly sized type such as named function -/// types (which are zero-sized). -pub mod r0_3_3 {} - -/// Release 0.3.2 (2017-02-10) -/// -/// * Minimum version required is now rustc 1.12.0; -/// * Updated dependency versions (most notably target_build_utils to 0.3.0) -pub mod r0_3_2 {} - -/// Release 0.3.1 (2016-10-01) -/// -/// * `Symbol` and `os::*::Symbol` now implement `Send` where `T: Send`; -/// * `Symbol` and `os::*::Symbol` now implement `Sync` where `T: Sync`; -/// * `Library` and `os::*::Library` now implement `Sync` (they were `Send` in 0.3.0 already). -pub mod r0_3_1 {} - -/// Release 0.3.0 (2016-07-27) -/// -/// * Greatly improved documentation, especially around platform-specific behaviours; -/// * Improved test suite by building our own library to test against; -/// * All `Library`-ies now implement `Send`. -/// * Added `impl From for Library` and `impl From for -/// os::platform::Library` allowing wrapping and extracting the platform-specific library handle; -/// * Added methods to wrap (`Symbol::from_raw`) and unwrap (`Symbol::into_raw`) the safe `Symbol` -/// wrapper into unsafe `os::platform::Symbol`. -/// -/// The last two additions focus on not restricting potential usecases of this library, allowing -/// users of the library to circumvent safety checks if need be. -/// -/// ## Beaking Changes -/// -/// `Library::new` defaults to `RTLD_NOW` instead of `RTLD_LAZY` on UNIX for more consistent -/// cross-platform behaviour. If a library loaded with `Library::new` had any linking errors, but -/// unresolved references weren’t forced to be resolved, the library would’ve “just worked”, -/// whereas now the call to `Library::new` will return an error signifying presence of such error. -/// -/// ## os::platform -/// * Added `os::unix::Library::open` which allows specifying arbitrary flags (e.g. `RTLD_LAZY`); -/// * Added `os::windows::Library::get_ordinal` which allows finding a function or variable by its -/// ordinal number; -pub mod r0_3_0 {} diff --git a/third_party/rust/libloading-0.4.3/src/lib.rs b/third_party/rust/libloading-0.4.3/src/lib.rs deleted file mode 100644 index 976e3b6cce11..000000000000 --- a/third_party/rust/libloading-0.4.3/src/lib.rs +++ /dev/null @@ -1,314 +0,0 @@ -//! A memory-safer wrapper around system dynamic library loading primitives. -//! -//!
