+
+Semantic version parsing and comparison.
+
+[![Build Status](https://api.travis-ci.org/steveklabnik/semver.svg?branch=master)](https://travis-ci.org/steveklabnik/semver)
+
+[Documentation](https://steveklabnik.github.io/semver)
+
+Semantic versioning (see http://semver.org/) is a set of rules for
+assigning version numbers.
+
+## SemVer and the Rust ecosystem
+
+Rust itself follows the SemVer specification, as does its standard libraries. The two are
+not tied together.
+
+[Cargo](https://crates.io), Rust's package manager, uses SemVer to determine which versions of
+packages you need installed.
+
+## Installation
+
+To use `semver`, add this to your `[dependencies]` section:
+
+```toml
+semver = "0.7.0"
+```
+
+And this to your crate root:
+
+```rust
+extern crate semver;
+```
+
+## Versions
+
+At its simplest, the `semver` crate allows you to construct `Version` objects using the `parse`
+method:
+
+```rust
+use semver::Version;
+
+assert!(Version::parse("1.2.3") == Ok(Version {
+ major: 1,
+ minor: 2,
+ patch: 3,
+ pre: vec!(),
+ build: vec!(),
+}));
+```
+
+If you have multiple `Version`s, you can use the usual comparison operators to compare them:
+
+```rust
+use semver::Version;
+
+assert!(Version::parse("1.2.3-alpha") != Version::parse("1.2.3-beta"));
+assert!(Version::parse("1.2.3-alpha2") > Version::parse("1.2.0"));
+```
+
+## Requirements
+
+The `semver` crate also provides the ability to compare requirements, which are more complex
+comparisons.
+
+For example, creating a requirement that only matches versions greater than or
+equal to 1.0.0:
+
+```rust
+use semver::Version;
+use semver::VersionReq;
+
+let r = VersionReq::parse(">= 1.0.0").unwrap();
+let v = Version::parse("1.0.0").unwrap();
+
+assert!(r.to_string() == ">= 1.0.0".to_string());
+assert!(r.matches(&v))
+```
+
+It also allows parsing of `~x.y.z` and `^x.y.z` requirements as defined at
+https://www.npmjs.org/doc/misc/semver.html
+
+**Tilde requirements** specify a minimal version with some updates:
+
+```notrust
+~1.2.3 := >=1.2.3 <1.3.0
+~1.2 := >=1.2.0 <1.3.0
+~1 := >=1.0.0 <2.0.0
+```
+
+**Caret requirements** allow SemVer compatible updates to a specified version,
+`0.x` and `0.x+1` are not considered compatible, but `1.x` and `1.x+1` are.
+
+`0.0.x` is not considered compatible with any other version.
+Missing minor and patch versions are desugared to `0` but allow flexibility for that value.
+
+```notrust
+^1.2.3 := >=1.2.3 <2.0.0
+^0.2.3 := >=0.2.3 <0.3.0
+^0.0.3 := >=0.0.3 <0.0.4
+^0.0 := >=0.0.0 <0.1.0
+^0 := >=0.0.0 <1.0.0
+```

+
+//! Semantic version parsing and comparison.
+//!
+//! Semantic versioning (see http://semver.org/) is a set of rules for
+//! assigning version numbers.
+//!
+//! ## SemVer overview
+//!
+//! Given a version number MAJOR.MINOR.PATCH, increment the:
+//!
+//! 1. MAJOR version when you make incompatible API changes,
+//! 2. MINOR version when you add functionality in a backwards-compatible
+//! manner, and
+//! 3. PATCH version when you make backwards-compatible bug fixes.
+//!
+//! Additional labels for pre-release and build metadata are available as
+//! extensions to the MAJOR.MINOR.PATCH format.
+//!
+//! Any references to 'the spec' in this documentation refer to [version 2.0 of
+//! the SemVer spec](http://semver.org/spec/v2.0.0.html).
+//!
+//! ## SemVer and the Rust ecosystem
+//!
+//! Rust itself follows the SemVer specification, as does its standard
+//! libraries. The two are not tied together.
+//!
+//! [Cargo](http://crates.io), Rust's package manager, uses SemVer to determine
+//! which versions of packages you need installed.
+//!
+//! ## Versions
+//!
+//! At its simplest, the `semver` crate allows you to construct `Version`
+//! objects using the `parse` method:
+//!
+//! ```{rust}
+//! use semver::Version;
+//!
+//! assert!(Version::parse("1.2.3") == Ok(Version {
+//! major: 1,
+//! minor: 2,
+//! patch: 3,
+//! pre: vec!(),
+//! build: vec!(),
+//! }));
+//! ```
+//!
+//! If you have multiple `Version`s, you can use the usual comparison operators
+//! to compare them:
+//!
+//! ```{rust}
+//! use semver::Version;
+//!
+//! assert!(Version::parse("1.2.3-alpha") != Version::parse("1.2.3-beta"));
+//! assert!(Version::parse("1.2.3-alpha2") > Version::parse("1.2.0"));
+//! ```
+//!
+//! If you explicitly need to modify a Version, SemVer also allows you to
+//! increment the major, minor, and patch numbers in accordance with the spec.
+//!
+//! Please note that in order to do this, you must use a mutable Version:
+//!
+//! ```{rust}
+//! use semver::Version;
+//!
+//! let mut bugfix_release = Version::parse("1.0.0").unwrap();
+//! bugfix_release.increment_patch();
+//!
+//! assert_eq!(Ok(bugfix_release), Version::parse("1.0.1"));
+//! ```
+//!
+//! When incrementing the minor version number, the patch number resets to zero
+//! (in accordance with section 7 of the spec)
+//!
+//! ```{rust}
+//! use semver::Version;
+//!
+//! let mut feature_release = Version::parse("1.4.6").unwrap();
+//! feature_release.increment_minor();
+//!
+//! assert_eq!(Ok(feature_release), Version::parse("1.5.0"));
+//! ```
+//!
+//! Similarly, when incrementing the major version number, the patch and minor
+//! numbers reset to zero (in accordance with section 8 of the spec)
+//!
+//! ```{rust}
+//! use semver::Version;
+//!
+//! let mut chrome_release = Version::parse("41.5.5377").unwrap();
+//! chrome_release.increment_major();
+//!
+//! assert_eq!(Ok(chrome_release), Version::parse("42.0.0"));
+//! ```
+//!
+//! ## Requirements
+//!
+//! The `semver` crate also provides the ability to compare requirements, which
+//! are more complex comparisons.
+//!
+//! For example, creating a requirement that only matches versions greater than
+//! or equal to 1.0.0:
+//!
+//! ```{rust}
+//! # #![allow(unstable)]
+//! use semver::Version;
+//! use semver::VersionReq;
+//!
+//! let r = VersionReq::parse(">= 1.0.0").unwrap();
+//! let v = Version::parse("1.0.0").unwrap();
+//!
+//! assert!(r.to_string() == ">= 1.0.0".to_string());
+//! assert!(r.matches(&v))
+//! ```
+//!
+//! It also allows parsing of `~x.y.z` and `^x.y.z` requirements as defined at
+//! https://www.npmjs.org/doc/misc/semver.html
+//!
+//! **Tilde requirements** specify a minimal version with some updates:
+//!
+//! ```notrust
+//! ~1.2.3 := >=1.2.3 <1.3.0
+//! ~1.2 := >=1.2.0 <1.3.0
+//! ~1 := >=1.0.0 <2.0.0
+//! ```
+//!
+//! **Caret requirements** allow SemVer compatible updates to a specified
+//! verion, `0.x` and `0.x+1` are not considered compatible, but `1.x` and
+//! `1.x+1` are.
+//!
+//! `0.0.x` is not considered compatible with any other version.
+//! Missing minor and patch versions are desugared to `0` but allow flexibility
+//! for that value.
+//!
+//! ```notrust
+//! ^1.2.3 := >=1.2.3 <2.0.0
+//! ^0.2.3 := >=0.2.3 <0.3.0
+//! ^0.0.3 := >=0.0.3 <0.0.4
+//! ^0.0 := >=0.0.0 <0.1.0
+//! ^0 := >=0.0.0 <1.0.0
+//! ```
+//!
+//! **Wildcard requirements** allows parsing of version requirements of the
+//! formats `*`, `x.*` and `x.y.*`.
+//!
+//! ```notrust
+//! * := >=0.0.0
+//! 1.* := >=1.0.0 <2.0.0
+//! 1.2.* := >=1.2.0 <1.3.0
