In this stream, we peel back the crust on the axum crate — https://github.com/tokio-rs/axum/ — and explore its interface, structure, and mechanisms. We talk about tower::Service, the Handler trait, Routers, and the State extractor. We also get into the way axum ensures at compile time that all handlers have access to the state that they'll need at runtime.
For more details about axum, see https://docs.rs/axum/latest/axum/.
