## Description

Axum is a web framework for the Rust programming language designed for building scalable and high-performance backend services. It provides a modular, asynchronous programming model that centers on a declarative routing engine, allowing developers to map HTTP requests to handler functions using a type-safe API.

The framework distinguishes itself through a robust request extraction system that leverages trait-based reflection to automatically parse and validate incoming data into strongly typed function arguments. By utilizing a standardized service abstraction, it enables the composition of modular middleware and request handlers into a unified processing pipeline, ensuring that cross-cutting concerns like authentication and tracing are handled consistently.

Beyond its core routing and extraction capabilities, the framework supports the development of structured web interfaces by automating the conversion of function return values into standard HTTP responses. It also provides a centralized model for error handling, ensuring that internal application failures are translated into predictable status codes and responses for reliable client communication.
