0.1.47

• Make swift-bridge-build silent by default. #143 #144 (thanks @antoniusnaumann)
  • This is useful for higher-level build tools that wrap swift-bridge-build.

0.1.46

• Support generating a Swift Equatable implementation for Rust types that implement PartialEq. #139 (thanks @NiwakaDev)

   // For example, the following is now possible:
  
   #[swift_bridge::bridge]
   mod ffi {
       extern "Rust" {
           #[swift_bridge(Equatable)]
           type SomeType;
       }
   }
  
   #[derive(PartialEq)]
   struct SomeType;

• Support generating a Swift Hashable implementation for Rust types that implement Hash. #140 (thanks @NiwakaDev)

   // For example, the following is now possible:
  
   #[swift_bridge::bridge]
   mod ffi {
       extern "Rust" {
           #[swift_bridge(Hashable, Equatable)]
           type SomeType;
       }
   }
  
   #[derive(Hash, PartialEq)]
   struct SomeType;

0.1.45

• Support the swift_name attribute on extern "Rust" exported functions. #128 (thanks @bes)

   // For example, the following is now possible
  
   #[swift_bridge::bridge]
   mod ffi {
       extern "Rust" {
           #[swift_bridge(swift_name = "someFunction")]
           fn some_function();
       }
   }

• Make RustVec methods public. #131 (thanks @onato)

0.1.44

• Make enums support the swift_name attribute. #126

  // For example, the following is now possible:
  
  #[swift_bridge::bridge]
  mod ffi {
      #[swift_bridge(swift_name = "EnumRename")]
      enum EnumName {
          Variant1,
          Variant2,
      }
  }

• Fix using the return_into attribute an already declared enum. #127

   // For example, the following is now possible:
  
   #[swift_bridge::bridge]
   mod ffi {
       #[swift_bridge(already_declared)]
       enum SomeEnum {}
   
       extern "Rust" {
           #[swift_bridge(return_into)]
           fn return_into_already_declared() -> SomeEnum;
       }
   }

0.1.43

• Show a spanned compile time error for invalid module items. #124

  #[swift_bridge::bridge]
  mod ffi {
      use std;
      fn foo() {}
  }
  
  // error: Only `extern` blocks, structs and enums are supported.
  //  --> tests/ui/invalid-module-item.rs:6:5
  //   |
  // 3 |     use std;
  //   |     ^^^^^^^^
  //
  // error: Only `extern` blocks, structs and enums are supported.
  //  --> tests/ui/invalid-module-item.rs:7:5
  //   |
  // 4 |     fn foo() {}
  //   |     ^^^^^^^^^^^

• Allow enums to use the #[already_declared] attribute. #125

   // For example, the following is now possible:
  
   use some_other_bridge_module::SomeEnum;
   
   #[swift_bridge::bridge]
   mod ffi {
       #[swift_bridge(already_declared)]
       enum SomeEnum {}
   
       extern "Rust" {
           fn print(val: SomeEnum);
       }
   }

0.1.42

• Support returning String from Swift -> Rust #123 (thanks @bes)

  // For example, the following is now possible:
  
  #[swift_bridge::bridge]
  mod foo {
      extern "Swift" {
          fn some_function () -> String;
      }
  }

0.1.41

• Support Vec<TransparentEnum> #117

  // For example, the following is now possible:
  
  #[swift_bridge::bridge]
  mod ffi {
      enum SomeEnum {
          VariantA,
          VariantB,
      }
  
      extern "Rust" {
          fn some_function(arg: Vec<SomeEnum>) -> Vec<SomeEnum>;
      }
  }

0.1.40

• Support opaque Swift types in results #115

  // For example, the following is now possible:
  
  #[swift_bridge::bridge]
  mod ffi {
      extern "Swift" {
          type SomeSwiftType;
  
          fn some_function(arg: Result<(), SomeSwiftType>);
      }
  }

0.1.39: Fix Box<dyn FnOnce> trailing comma (#113)

• Fix compile time error from trailing commas after a boxed FnOnce #113

  // For example, the following is now possible:
  
  #[swift_bridge::bridge]
  mod ffi {
      extern "Swift" {
          fn swift_func_takes_callback(
              // Note the trailing comma after the `FnOnce(..)`
              arg: Box<dyn FnOnce(Result<SomeRustType, String>), >
          );
      }
  }

0.1.38

• Add support for Result<T, E> #111

  // For example, the following is now possible:
  
  use some_crate::SomeRustType;
  
  #[swift_bridge::bridge]
  mod ffi {
      extern "Swift" {
          fn swift_func_takes_callback(
              arg: Box<dyn FnOnce(Result<SomeRustType, String>)>,
          );
      }
  
      extern "Rust" {
          type SomeRustType;
  
          #[swift_bridge::init]
          fn new () -> SomeRustType;
      }
  }
