Rustc Semver

This crate provides a minimalistic parser for Rust versions.

Description

The parser will only accept Versions in the form

<major>.<minor>.<patch>

and 3 special versions:

This covers every version of rustc that were released to date.

There are 2 functions to create a RustcVersion:

const RustcVersion::new(u32, u32, u32): This is mainly used to create constants
RustcVersion::parse(&str): Usually you want to parse a version with this function

If you have a RustcVersion you can compare them, like you would expect:

assert!(RustcVersion::parse("1.42.0")? < RustcVersion::parse("1.43")?);

If you want to check whether one version meets another version according to the Caret Requirements, there is the method RustcVersion::meets:

assert!(RustcVersion::new(1, 48, 0).meets(RustcVersion::parse("1.42")?));
