It is protocol agnostic, but is designed around a request / response pattern. If your protocol is entirely stream based, Tower may not be a good fit. ## Supported Rust Versions Tower will keep a rolling MSRV (minimum supported Rust version) policy of **at least** 6 months. When increasing the MSRV, the new Rust version must have been released at least six months ago. The current MSRV is 1.64.0. ## Getting Started If you're brand new to Tower and want to start with the basics we recommend you check out some of our [guides]. ## License This project is licensed under the [MIT license](LICENSE). ### Contribution Unless you explicitly state otherwise, any contribution intentionally submitted for inclusion in Tower by you, shall be licensed as MIT, without any additional terms or conditions.
