• Support returning Result<T, E> where T and E are opaque Rust types. #149

  // For example, the following is now possible:
  
  #[swift_bridge::bridge]
  mod ffi {
      extern "Rust" {
          type TypeA;
          type TypeB;
  
          fn some_function() -> Result<TypeA, TypeB>;
  
          fn print_info(self: &TypeB);
      }
  }

  // Swift
  
  do {
      let typeA = try some_function()
  } catch let typeB as TypeB {
      typeB.print_info()
  }

• Support Option<Vec<T>> where T is a primitive type. #147 (thanks @NiwakaDev)

  // For example, the following is now possible:
  
  #[swift_bridge::bridge]
  mod ffi {
      extern "Rust" {
          fn some_function(arg: Option<Vec<u8>>) -> Option<Vec<i64>>;
      }
  }

• Optimize RustStr's Swift Equatable protocol implementation. #151 (thanks @NiwakaDev)

• Add compile time error messages for invalid args_into attributes. #145 (thanks @NiwakaDev)
