  use futures_async_stream::async_stream;

  trait Foo {
      #[async_stream(boxed, item = u32)]
      async fn method(&mut self);
  }

  struct Bar(u32);

  impl Foo for Bar {
      #[async_stream(boxed, item = u32)]
      async fn method(&mut self) {
          while self.0 < u32::MAX {
              self.0 += 1;
