axum

Ergonomic web framework for Rust, built on tokio and hyper.

What it is

axum uses extractors — types implementing FromRequest — to declare what each handler needs from an HTTP request: JSON body, path parameters, headers, or auth tokens. Routing uses method-specific helpers and supports nested routers and tower middleware layers.

Why it is commonly used

One of the leading web framework choices for Rust services. Used for REST APIs, HTTP backends, and microservices. Tightly integrated with the tokio/tower/hyper stack, making it the natural choice when already using that ecosystem.
