Rustc Semver

This crate provides a minimalistic parser for Rust versions.

Archive Note

This crate was mainly used in Clippy. But since then, a rustc implementation has been created. Clippy moved to that in rust-clippy#13243, so this crate will no longer be maintained.

Description

The parser will only accept Versions in the form

<major>.<minor>.<patch>

and 3 special versions:

• 1.0.0-alpha
• 1.0.0-alpha.2
• 1.0.0-beta

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

Usage

There are 2 functions to create a RustcVersion:

1. const RustcVersion::new(u32, u32, u32): This is mainly used to create constants
2. 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")?));
