v0.22.0

[v0.22.0] - 2024-02-07

Another breaking release where a new ResponsePayload type is introduced in order
to make it possible to determine whether a response has been processed.

Unfortunately, the IntoResponse trait was modified to enable that
and some minor changes were made to make more fields private to avoid further
breakage.

Example of the async ResponsePayload API

#[rpc(server)]
pub trait Api {
	#[method(name = "x")]
	fn x(&self) -> ResponsePayload<'static, String>;
}

impl RpcServer for () {
	fn x(&self) -> ResponsePayload<'static, String> {
		let (rp, rp_done) = ResponsePayload::success("ehheeheh".to_string()).notify_on_completion();

		tokio::spawn(async move {
			if rp_done.await.is_ok() {
				do_task_that_depend_x();
			}
		});

		rp
	}
}

Roadmap
