Rust crates: async_stream (Twitch live stream 2023-02-20)
1In this video, we continued building our lastfm crate and explored how to create async iterators (streams) in tokio using the async_stream crate (https://crates.io/crates/async-stream). I also showcase how to use the Insta crate for snapshot testing (https://crates.io/crates/insta).
