Warp: Lightweight & High-Performance Web Framework
A non-blocking web framework for Rust, built on Tokio, offering easy routing, middleware, filters and quick development of REST APIs and web services.
What is Warp web framework?
Warp is a web framework for the Rust programming language focused on ease of use and high performance. Here are some key things to know about Warp:
- Non-blocking and asynchronous - It builds on top of Tokio which utilizes Rust's async/await syntax for asynchronous I/O operations. This allows Warp applications to handle thousands of concurrent connections efficiently.
- Fast - Benchmarks clock Warp as one of the fastest web frameworks around, thanks to Rust's lightweight abstraction costs and focus on performance.
- Middleware and Filters - Warp provides a simple way to compose reusable logic through middleware and filters. Filters specifically allow manipulating requests and responses as they go through the stack.
- Minimal and flexible - With Warp you get just a robust routing mechanism out of the box. There is no bundled support for sessions, database connections, templates, etc. This allows selecting other crates suited for the task.
- Easy to learn API - Warp aims to have an intuitive API for quickly building web services. The docs provide many examples for common use cases.
Overall, if you need to build a fast, concurrent web service, REST API, or middleware layer, Warp is a solid choice to consider among Rust web frameworks.
