| //! |
| //! This module contains a definition of the `Version` type. The `Version` |
| //! type is intended to be accessed through the root of the crate |
| //! (`http::Version`) rather than this module. |
| //! |
| //! The `Version` type contains constants that represent the various versions |
| //! of the HTTP protocol. |
| //! |
| //! # Examples |
| //! |
| //! ``` |
| //! use http::Version; |
| //! |
| //! let http11 = Version::HTTP_11; |
| //! let http2 = Version::HTTP_2; |
| //! assert!(http11 != http2); |
| //! |
| //! println!("{:?}", http2); |
| //! ``` |
