Axum

Axum is a web application framework that focuses on ergonomics and modularity.

Features:

• Route requests to handlers with a macro free API.
• Declaratively parse requests using extractors.
• Simple and predictable error handling model.
• Generate responses with minimal boilerplate.
• Take full advantage of the tower and tower-http ecosystem of middleware, services, and utilities.

In particular the last point is what sets axum apart from other frameworks. axum doesn't have its own middleware system but instead uses tower::Service. This means axum gets timeouts, tracing, compression, authorization, and more, for free. It also enables you to share middleware with applications written using hyper or tonic.
