From ecf3474223ca3d16a10f12dc2272e3b0ed72c1bb Mon Sep 17 00:00:00 2001 From: Daniel Mueller Date: Wed, 2 Jan 2019 21:14:10 -0800 Subject: Update nitrokey crate to 0.2.3 This change updates the nitrokey crate to version 0.2.3. This version bumps the rand crate used to 0.6.1, which in turn requires an additional set of dependencies.

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. +//!
