Unreleased

0.4.9 - 2020-04-14

• Fixed lifetime inference error when associated types are used in fields.

• Fixed compile error with tuple structs with where clauses.

• #[project] attribute can now be used for if let expressions.

0.4.8 - 2020-01-27

• Ensured that users cannot implement PinnedDrop without proper attribute argument.

0.4.7 - 2020-01-20

• Fixed compile error with dyn types.

0.4.4 - 2019-10-17

• Fixed an issue where PinnedDrop implementations can call unsafe code without an unsafe block.

0.4.3 - 2019-10-15 - YANKED

• #[pin_project] can now interoperate with #[cfg_attr()].

• #[pin_project] can now interoperate with #[cfg()] on tuple structs and tuple variants.

0.4.2 - 2019-09-29 - YANKED

• Fixed support for DSTs(Dynamically Sized Types).

0.4.1 - 2019-09-26 - YANKED

• Fixed an issue that caused an error when using #[pin_project] on a type that has #[pin] + !Unpin field with no generics or lifetime.

0.4.0 - 2019-09-25 - YANKED

• Pin projection has become a safe operation. In the absence of other unsafe code that you write, it is impossible to cause undefined behavior.

• #[unsafe_project] attribute has been replaced with #[pin_project] attribute. (#18, #33)

• The Unpin argument has been removed - an Unpin impl is now generated by default.

• Drop impls must be specified with #[pinned_drop] instead of via a normal Drop impl. (#18, #33, #86)

• Unpin impls must be specified with an impl of UnsafeUnpin, instead of implementing the normal Unpin trait.

• #[pin_project] attribute now determines the visibility of the projection type/method is based on the original type.

• #[pin_project] can now be used for public type with private field types.

• #[pin_project] can now interoperate with #[cfg()].

• Added project_ref method to #[pin_project] types.

• Added #[project_ref] attribute.

• Removed "project_attr" feature and always enable #[project] attribute.

• #[project] attribute can now be used for impl blocks.

• #[project] attribute can now be used for use statements.

• #[project] attribute now supports match expressions at the position of the initializer expression of let expressions.

Changes since the 0.4.0-beta.1 release:

• Fixed an issue that caused an error when using #[pin_project(UnsafeUnpin)] and not providing a manual UnsafeUnpin implementation on a type with no generics or lifetime.

0.4.0-beta.1 - 2019-09-21

• Changed the argument type of project method back to self: Pin<&mut Self>.

• Removed "project_attr" feature and always enable #[project] attribute.

• Removed "renamed" feature.

• #[project] attribute can now be used for use statements.

• Added project_ref method and #[project_ref] attribute.

• #[pin_project] attribute now determines the visibility of the projection type/method is based on the original type.

0.4.0-alpha.11 - 2019-09-11

• Changed #[pinned_drop] to trait implementation.

  #[pinned_drop]
  impl<T> PinnedDrop for Foo<'_, T> {
      fn drop(mut self: Pin<&mut Self>) {
          **self.project().was_dropped = true;
      }
  }
  

• Added some examples and generated code.

• Improve error messages.

0.4.0-alpha.10 - 2019-09-07

• #[pin_project] can now interoperate with #[cfg()].

• Improved documentation.

0.4.0-alpha.9 - 2019-09-05

• Added 'project_into' method to #[pin_project] types. This can be useful when returning a pin projection from a method.

  fn get_pin_mut(self: Pin<&mut Self>) -> Pin<&mut T> {
      self.project_into().pinned
  }
  

• Prevented UnpinStruct from appearing in the document by default. See taiki-e/pin-project#71 for more details.

0.4.0-alpha.8 - 2019-09-03

• Improved document of generated code.. Also added an option to control the document of generated code. See taiki-e/pin-project#62 for more details.

• Improved error messages

0.4.0-alpha.7 - 2019-09-02

• Applied #[allow(dead_code)] to generated types.

0.4.0-alpha.6 - 2019-09-01

• #[project] attribute can now be used for impl blocks.

• #[pin_project] attribute can now detect that the type used does not have its own drop implementation without actually implementing drop. This removed some restrictions.

0.4.0-alpha.2 - 2019-08-13
