Differences between channel in tokio::sync::mpsc and crossbeam

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

The difference is that the Tokio channel is asynchronous. This means that send and recv are async functions that must be awaited for you to call them, meaning that they can only be used in async code. The crossbeam channel is not async, and its send and recv methods will block instead. You cannot use crossbeam in async code due to the issues described in this article.

If you are sending messages between async and non-async code, then Tokio's documentation explains what you should do. Read about that here.


This is helpful. Thanks!
