• Support Failable initializers. #276 (thanks @NiwakaDev)

  // Rust
  
  #[swift_bridge::bridge]
  mod ffi {
      extern "Rust" {
          #[swift_bridge(Equatable)]
          type FailableInitType;
  
          #[swift_bridge(init)]
          fn new() -> Option<FailableInitType>;
      }
  }

  // Swift
  
  let failableInitType = FailableInitType()
  if failableInitType == nil {
      // ...
  } else {
     // ...
  }

• Support Throwing initializers #287 (thanks @NiwakaDev)

  // Rust
  
  #[swift_bridge::bridge]
  mod ffi {
      enum ResultTransparentEnum {
          NamedField { data: i32 },
          UnnamedFields(u8, String),
          NoFields,
      }
      extern "Rust" {
          type ThrowingInitializer;
          #[swift_bridge(init)]
          fn new(succeed: bool) -> Result<ThrowingInitializer, ResultTransparentEnum>;
          fn val(&self) -> i32;
      }
  }

  // Swift
  
  do {
      let throwingInitializer = try ThrowingInitializer(false)
  } catch let error as ResultTransparentEnum {
      //...
  } catch {
      //...
  }
