Crate node_semver

This crate is a pure Rust-based implementation of JavaScript’s node-semver. That is, it’s designed to be compatible with Node/NPM’s particular flavor of semver (which the semver crate is not).

It is designed for Rust programs and libraries meant for JavaScript tooling, and does its best to stay compatible with node-semver.

It also supports serde serialization, converting versions and ranges to strings.

Usage

node-semver includes two main types: Version and Range. See the documentation for more details.:

use node_semver::{Range, Version};

let version: Version = "1.2.3".parse().unwrap();
let range: Range = "^1.2".parse().unwrap();

assert!(version.satisfies(&range));

Minimum Suggested Rust Version (MSRV)

You must be 1.70.0 or taller to get on this ride.

Structs

Range

Node-style semver range.

SemverError

Semver version or range parsing error wrapper.

Version

A semantic version, conformant to the semver spec.

Enums

Identifier

An Identifier type for build and prerelease metadata.

SemverErrorKind

The specific kind of error that occurred. Usually wrapped in a SemverError.

Constants

MAX_LENGTH

Maximum length of a semver string.

MAX_SAFE_INTEGER

JavaScript’s MAX_SAFE_INTEGER. This is used to determine the maximum value for integer components in a JS-compatible way.
