# Rust async playground
+
+## Notes
+
+Research started in 2019 - https://users.rust-lang.org/t/designing-an-async-flow-of-data/29148 and got pointed to `Stream` and `Sink` which are the appropriate abstractions for async *iteration*.
+
+They weren't stable at the time, but seem to be maturing in the `futures` crate:
+
+https://docs.rs/futures/0.3.6/futures/sink/trait.Sink.html
+
+https://docs.rs/futures/0.3.6/futures/stream/trait.Stream.html
+
+This is the relevant chapter in the Rust Async Book - https://rust-lang.github.io/async-book/05_streams/02_iteration_and_concurrency.html
