Python PEP-440 Version Parser
This package allows for parsing Python PEP-440 version numbers and for comparisons between PEP-440 version numbers.
[dependencies] pyver = "1"
The following is an example for initilizing and comparing two version strings
use pyver::PackageVersion; let a = PackageVersion::new("v1.0a2.dev456").unwrap(); let b = PackageVersion::new("v1.0a2.dev457").unwrap(); assert_eq!(a < b, true);
Comparing single version components
use pyver::PackageVersion; let a = PackageVersion::new("1!1.323.dev2").unwrap(); let b = PackageVersion::new("v3.2.dev2").unwrap(); // Check that both have the same dev version assert_eq!(a.dev, b.dev);
Seperation of version identifiers
use pyver::PackageVersion; let version = PackageVersion::new("v1.23.dev2").unwrap(); println!("{:?}", version.release.major); // > 1 println!("{:?}", version.release.minor); // > 2 println!("{:?}", version.dev); // > Some(DevHead { dev_num: Some(2) })
