Differences between channel in tokio::sync::mpsc and crossbeam ...
April 17, 2023 - To a novice like me they seem to be interchangeable. I can only guess that tokio's channels could be better for async somehow. But that's just me taking a shot in the dark. Looking to get some info about the differences from the experts. Thanks

September 28, 2020 - Hi, tokio has it's own implementation of mpsc queue, which differs from implementation in futures. Main difference for me now is that tokio's Sender does not implement Sink trait, which is something I miss. So questions - why two different implementations? Is anything wrong with futures' mpsc ...

How to respond streaming data from Receiver? · tokio-rs/axum · ...

You can use ReceiverStream to convert the receiver into a stream and then use SSE similar to what's shown here.

However these days it's more common to use websockets than sse. More details on that here. There is a complete chat app example here.
