Notable changes to this crate will be documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).

|
|
## Unreleased - YYYY-MM-DD
|
|
|
|
## 2.0.0-pre.2 - 2022-08-28
|
|
|
|
### Added
|
|
* Added `EncodeConvert` trait to help with correctly handling `BOOL`/`bool`.
|
|
|
|
### Changed
|
|
* **BREAKING**: Remove the lifetime specifier from `Encoding`, since the non
|
|
-`'static` version was essentially useless.
|
|
|
|
### Fixed
|
|
* Fixed the encoding output and comparison of structs behind pointers.
|
|
|
|
### Removed
|
|
* **BREAKING**: `bool` (and `AtomicBool`) no longer implements `Encode`, since
|
|
that was difficult to use correctly. See the `EncodeConvert` trait, or use
|
|
`objc2::runtime::Bool` instead.
|
|
|
|
|
|
## 2.0.0-pre.1 - 2022-07-19
|
|
|
|
### Added
|
|
* Added `Encoding::Atomic`.
|
|
* Implement `Encode` and `RefEncode` for `std::sync::atomic` types.
|
|
|
|
### Changed
|
|
* **BREAKING**: Renamed `Encoding::C_U_LONG` to `Encoding::C_ULONG`.
|
|
|
|
|
|
## 2.0.0-pre.0 - 2022-06-13
|
|
|
|
### Added
|
|
* Added `Encoding::C_LONG` and `Encoding::C_U_LONG` to help with platform
|
|
compatibility; use these instead of `c_long::ENCODING` and
|
|
`c_ulong::ENCODING`.
|
|
* Implement `Encode` and `RefEncode` for `MaybeUninit<T>`, where `T` is
|
|
properly bound.
|
|
|
|
### Changed
|
|
* **BREAKING**: Sealed the `EncodeArguments` trait.
|
|
* **BREAKING**: Add type argument to `Encoding::BitField`.
|
|
|
|
### Removed
|
|
* **BREAKING**: Removed `PartialEq` impl between `str` and `Encoding` since it
|
|
was incorrect (it violated the trait requirements).
|
|
* **BREAKING**: Removed `Encode` and `RefEncode` implementations for `Pin`
|
|
since it may not be sound.
|
|
|
|
|
|
## 2.0.0-beta.2 - 2022-01-03
|
|
|
|
### Added
|
|
* Implement `Hash` for `Encoding`.
|
|
|
|
### Changed
|
|
* Improved documentation.
|
|
|
|
|
|
## 2.0.0-beta.1 - 2021-12-22
|
|
|
|
### Added
|
|
* `Encoding::equivalent_to`, `Encoding::equivalent_to_str` and
|
|
`Encoding::equivalent_to_start_of_str` methods for more precise comparison
|
|
semantics.
|
|
* Added `Encode` and `RefEncode` implementations for `Option` function
|
|
pointers.
|
|
|
|
### Changed
|
|
* Discourage comparing `str` with `Encoding` using `PartialEq`. This trait
|
|
impl might get removed in a future version.
|
|
|
|
|
|
## 2.0.0-beta.0 - 2021-11-22
|
|
|
|
### Added
|
|
* **BREAKING**: Add `Encoding::LongDouble`, `Encoding::FloatComplex`,
|
|
`Encoding::DoubleComplex` and `Encoding::LongDoubleComplex`.
|
|
* Implement `RefEncode` for all number types that implement `Encode` (`bool`,
|
|
`i8`, `usize`, `f32`, `NonZeroU32`, and so on).
|
|
* Implement `RefEncode` for `*const c_void` and `*mut c_void` (allowing
|
|
`void**` in C).
|
|
* Implement `Encode` and `RefEncode` for `Wrapping<T>`, where `T` is properly
|
|
bound.
|
|
|
|
### Changed
|
|
* **BREAKING**: Make `Encoding` `#[non_exhaustive]`. This will help us in
|
|
evolving the API while minimizing further breaking changes.
|
|
* Discourage using `bool::ENCODING`; use `objc2::Bool::ENCODING` instead.
|
|
* Discourage using `()::ENCODING` for anything other than as a function return
|
|
type.
|
|
|
|
|
|
## 2.0.0-alpha.1 - 2021-09-01
|
|
|
|
### Added
|
|
* Improved documentation.
|
|
* Add `RefEncode` trait, which represents types whoose pointers has an
|
|
encoding. This means you now only have to implement `RefEncode`, and not
|
|
both `&Encode` and `&mut Encode`.
|
|
Additionally, encodings of pointers to pointers (to pointers, and so on) are
|
|
now supported.
|
|
* Implement `Encode` for `NonZeroX` and `Option<NonZeroX>` integer types.
|
|
* Implement `RefEncode` for arrays.
|
|
* Implement `Encode` and `RefEncode` for (where `T` is properly bound):
|
|
- `ManuallyDrop<T>`
|
|
- `Pin<T>`
|
|
- `NonNull<T>`
|
|
- `Option<NonNull<T>>`
|
|
* Add `EncodeArguments` trait, to represent an ordered group of functions
|
|
arguments, where each argument has an Objective-C type-encoding.
|
|
Previously in the `objc` crate.
|
|
* Implement `Encode` and `RefEncode` for some `extern "C" fn` pointers.
|
|
|
|
### Removed
|
|
* **BREAKING**: Removed automatic `*const T: Encode` and `*mut T: Encode`
|
|
impls when when `&T: Encode` and `&mut T: Encode` was implemented.
|
|
|
|
Implement `T: RefEncode` instead!
|
|
|
|
|
|
## 2.0.0-alpha.0 - 2021-09-01
|
|
|
|
### Added
|
|
* Improved documentation.
|
|
* Support for targets with pointer-width 16
|
|
* Implement `Encode` for all array lengths using const-generics.
|
|
* Implement `Encode` for unsized pointer types as well.
|
|
|
|
### Changed
|
|
* **BREAKING**: Forked the project, so it is now available under the name
|
|
`objc2-encode`.
|
|
* **BREAKING**: Changed type in `Encoding::BitField` from `u32` to `u8`.
|
|
* **BREAKING**: Changed type in `Encoding::Array` from `u32` to `usize`.
|
|
* **BREAKING**: Loosen `'static` bounds on references implementing `Encode`.
|
|
|
|
|
|
## [1.1.0] (`objc-encode` crate) - 2019-10-16
|
|
|
|
### Added
|
|
* Implement `Encode` for arrays with up to 32 elements.
|
|
|
|
### Changed
|
|
* Simplify internal encoding comparison.
|
|
|
|
|
|
## [1.0.0] (`objc-encode` crate) - 2019-03-25
|
|
|
|
### Added
|
|
* Implement `PartialEq` between `Encoding` and `&str`.
|
|
|
|
### Changed
|
|
* **BREAKING**: Make `Encoding` an enum instead of a trait, yielding a vastly
|
|
different design. This makes use of associated constants.
|
|
* **BREAKING**: Rename `Encode::CODE` to `Encode::ENCODING`.
|
|
* Update to Rust 2018.
|
|
|
|
### Removed
|
|
* `libc` dependency.
|
|
|
|
|
|
## [0.0.3] (`objc-encode` crate) - 2017-04-30
|
|
|
|
### Fixed
|
|
* Compilation on versions prior to Rust `1.15`.
|
|
|
|
|
|
## [0.0.2] (`objc-encode` crate) - 2017-02-20
|
|
|
|
### Added
|
|
* **BREAKING**: `Display` requirement for encodings.
|
|
* Implement `PartialEq` for encodings.
|
|
* Implement `Encode` for pointers when references do.
|
|
|
|
### Fixed
|
|
* `IndexEncodingsComparator`.
|
|
* Compilation with older Rust versions.
|
