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

The format is based on Keep a Changelog.

Unreleased - YYYY-MM-DD

0.5.1 - 2024-05-21

Deprecated

• Deprecated the apple Cargo feature flag, it is assumed by default on Apple platforms.

0.5.0 - 2024-04-17

Added

• BREAKING: Added Block::copy to convert blocks to RcBlock. This replaces StackBlock::copy, but since StackBlock implements Deref, this will likely work as before.
• Added RcBlock::new(closure) as a more efficient and flexible alternative to StackBlock::new(closure).copy().
• Added BlockFn trait to describe valid dyn Fn types for blocks.

Changed

• BREAKING: Changed how blocks specify their parameter and return types. We now use dyn Fn so that it is more clear what the parameter and return types are. This also allows us to support non-'static blocks.

  // Before
  let block: &Block<(), ()>;
  let block: &Block<(i32,), i32>;
  let block: &Block<(i32, u32), (i32, u32)>;
  
  // After
  let block: &Block<dyn Fn()>;
  let block: &Block<dyn Fn(i32) -> i32>;
  let block: &Block<dyn Fn(i32, u32) -> (i32, u32)>;
  // Now possible
  let block: &Block<dyn Fn() + '_>; // Non-'static block
  

• BREAKING: Make Block::call safe, and instead move the upholding of the safety invariant to the type itself.

• BREAKING: Renamed RcBlock::new(ptr) to RcBlock::from_raw(ptr).

• BREAKING: Made RcBlock use the null-pointer optimization; RcBlock::from_raw and RcBlock::copy now return an Option.

• BREAKING: Only expose the actually public symbols _Block_copy, _Block_release, _Block_object_assign, _Block_object_dispose, _NSConcreteGlobalBlock, _NSConcreteStackBlock and Class in ffi module.

• BREAKING: Renamed IntoConcreteBlock to IntoBlock, moved associated type Output to be a generic parameter, and added lifetime parameter.`

• No longer use the block-sys crate for linking to the blocks runtime.

• Renamed ConcreteBlock to StackBlock, and added a lifetime parameter. The old name is deprecated.

• Added Copy implementation for StackBlock.

Removed

• BREAKING: Removed BlockArguments in favour of BlockFn, which describes both the parameter types, as well as the return type.

Fixed

• BREAKING: StackBlock::new now requires the closure to be Clone. If this is not desired, use RcBlock::new instead.
• Relaxed the F: Debug bound on StackBlock's Debug implementation.
• BREAKING: Fixed GlobalBlock not having the correct variance. This may break if you were using lifetimes in your parameters, as those are now a bit too restrictive.

0.4.0 - 2023-12-03

Changed

• BREAKING: Updated objc2 dependency to v0.5.0.

0.3.0 - 2023-07-31

Fixed

• Bumped version number to ensure that this crate can be compiled together with code that depends on pre-releases of 0.2.0.

0.2.0 - 2023-06-20

Changed

• BREAKING: Updated objc2 dependency to v0.4.0.

0.2.0-alpha.8 - 2023-02-07

Changed

• BREAKING: Use traits from objc2 v0.3.0-beta.5 instead of objc2-encode.
• Updated ffi module to block-sys v0.2.0.

0.2.0-alpha.7 - 2022-12-24

Changed

• Improve efficiency when a block doesn't need to be destroyed.
• BREAKING: Updated objc2-encode to v2.0.0-pre.3.
• Updated ffi module to block-sys v0.1.0-beta.2.

0.2.0-alpha.6 - 2022-08-28

Changed

• BREAKING: Updated objc2-encode to v2.0.0-pre.2.
• Updated ffi module to block-sys v0.1.0-beta.1.

Fixed

• BREAKING: Cleaned up BlockArguments trait, it is now sealed and a subtrait of EncodeArguments.
• BREAKING: Cleaned up IntoConcreteBlock trait, it is now sealed and the associated output type has been renamed to Output.

0.2.0-alpha.5 - 2022-07-19

Added

• Implemented Debug for Block, ConcreteBlock, RcBlock and GlobalBlock.

Changed

• BREAKING: Updated objc2-encode to v2.0.0-pre.1.
• Updated ffi module to block-sys v0.1.0-beta.0.

0.2.0-alpha.4 - 2022-06-13

Changed

• BREAKING: Updated objc2-encode to v2.0.0-pre.0.
• BREAKING: Updated ffi module to block-sys v0.0.4. This tweaks the types of a lot of fields and parameters, and makes the apple runtime always be the default.

Removed

0.2.0-alpha.3 - 2022-01-03

Changed

• Changed global_block! macro to take an optional semicolon at the end.
• Improved documentation.
• BREAKING: Updated ffi module to block-sys v0.0.3.

0.2.0-alpha.2 - 2021-12-22

Added

• GlobalBlock and corresponding global_block! macro, allowing statically creating blocks that don't reference their environment.

Changed

• BREAKING: Updated ffi module to block-sys v0.0.2. This means that Class is now !UnwindSafe.

0.2.0-alpha.1 - 2021-11-22

Added

• Proper GNUStep support using block-sys. See that crate for usage.
• Export block-sys as ffi module.

Removed

• Dependency on objc_test_utils.

Fixed

• ConcreteBlock no longer allocates block descriptors on the heap.
• Better unwind safety in ConcreteBlock::copy.

0.2.0-alpha.0 - 2021-10-28

Added

• BREAKING: Blocks now require that parameter and return types implement objc2_encode::Encode. This is a safety measure to prevent creating blocks with invalid parameters.

• Update to 2018 edition.

Changed

• BREAKING: Forked the project, so it is now available under the name block2.
