Decrusting the tokio crate
In this stream, we peeled back the crust on the tokio crate — https://github.com/tokio-rs/tokio/ — and explored its interface, structure, and mechanisms. We talked about blocking, cancellation, spawning, and mechanisms for synchronization. We also dug into some of what goes on under the hood where that ends up being relevant to you as an application author!
For more details about tokio, see https://docs.rs/tokio/.
