//! HTTP version
//!
//! 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);
//! ```
use std::fmt;
/// Represents a version of the HTTP spec.
#[derive(PartialEq, PartialOrd, Copy, Clone, Eq, Ord, Hash)]
pub struct Version(Http);
impl Version {
/// `HTTP/0.9`
pub const HTTP_09: Version = Version(Http::Http09);
/// `HTTP/1.0`
pub const HTTP_10: Version = Version(Http::Http10);
/// `HTTP/1.1`
pub const HTTP_11: Version = Version(Http::Http11);
/// `HTTP/2.0`
pub const HTTP_2: Version = Version(Http::H2);
/// `HTTP/3.0`
pub const HTTP_3: Version = Version(Http::H3);
