1.0.1

• Fix warnings when #[pin_project] attribute used within macro_rules! macros.

1.0.0

• Remove deprecated #[project], #[project_ref], and #[project_replace] attributes.

  Name the projected type by passing an argument with the same name as the method to the #[pin_project] attribute instead:

  - #[pin_project]
  + #[pin_project(project = EnumProj)]
    enum Enum<T> {
        Variant(#[pin] T),
    }
  
  - #[project]
    fn func<T>(x: Pin<&mut Enum<T>>) {
  -     #[project]
        match x.project() {
  -         Enum::Variant(_) => { /* ... */ }
  +         EnumProj::Variant(_) => { /* ... */ }
        }
    }

• Remove deprecated Replace argument from #[pin_project] attribute. Use project_replace argument instead.

• Optimize code generation when used on enums.

• Raise the minimum supported Rust version of this crate from Rust 1.34 to Rust 1.37.

• Suppress explicit_outlives_requirements, box_pointers, clippy::large_enum_variant, clippy::pattern_type_mismatch, clippy::implicit_return, and clippy::redundant_pub_crate lints in generated code. (#276, #277, #284)

• Diagnostic improvements.

Changes since the 1.0.0-alpha.1 release:

• Fix drop order of pinned fields in project_replace

• Update minimal version of syn to 1.0.44

0.4.27

• Update minimal version of syn to 1.0.44

0.4.26

• Fix drop order of pinned fields in project_replace

0.4.25

• Suppress drop_bounds lint, which will be added to rustc in the future. See #272 for more details.

  (Note: 1.0.0-alpha.1 already contains this change.)

0.4.24

• Fix compatibility of generated code with forbid(future_incompatible)

  Note: This does not guarantee compatibility with forbid(future_incompatible) in the future.
  If rustc adds a new lint, we may not be able to keep this.

1.0.0-alpha.1

• Remove deprecated #[project], #[project_ref], and #[project_replace] attributes.

  Name the projected type by passing an argument with the same name as the method to the #[pin_project] attribute instead:

  - #[pin_project]
  + #[pin_project(project = EnumProj)]
    enum Enum<T> {
        Variant(#[pin] T),
    }
  
  - #[project]
    fn func<T>(x: Pin<&mut Enum<T>>) {
  -     #[project]
        match x.project() {
  -         Enum::Variant(_) => { /* ... */ }
  +         EnumProj::Variant(_) => { /* ... */ }
        }
    }

• Remove deprecated Replace argument from #[pin_project] attribute. Use project_replace argument instead.

• Optimize code generation when used on enums.

• Suppress explicit_outlives_requirements, box_pointers, clippy::large_enum_variant, clippy::pattern_type_mismatch, and clippy::implicit_return lints in generated code. (#276, #277)

• Diagnostic improvements.

See also tracking issue for 1.0 release.

0.4.23

• Fix compile error with ?Sized type parameters.

0.4.22

• Documentation improvements.

0.4.21

• Deprecated #[project], #[project_ref], and #[project_replace] attributes due to some unfixable limitations.

  Consider naming the projected type by passing an argument with the same name as the method to the #[pin_project] attribute instead.

  use pin_project::pin_project;
  use std::pin::Pin;
  
  #[pin_project(project = EnumProj)]
  enum Enum<T> {
      Variant(#[pin] T),
  }
  
  fn func<T>(x: Pin<&mut Enum<T>>) {
      match x.project() {
          EnumProj::Variant(y) => {
              let _: Pin<&mut T> = y;
          }
      }
  }

  See #225 for more details.

• Support Self in fields and generics in type definitions.

• Fix errors involving "self value is a keyword only available in methods with self parameter" in apparently correct code.

• Diagnostic improvements.
