In plain English

Axum is a web framework for building backend servers in Rust. It handles the core job of a web server: receiving HTTP requests from users or other systems, routing them to the right handler functions, and sending back responses. It is designed to be ergonomic (pleasant to write) and modular (easy to combine with other components).
