Build with Naz : Rust async, non-blocking, concurrent, parallel, event loops, graceful shutdown

In this article, video, and repo learn effective async Rust using real world patterns that show up consistently when creating non blocking, async, event loops, using channels. Delve into implementing the Future trait and async executor manually. Also explore graceful shutdown, when not to use async, and how to think about testing async code.
