vercomp

A Rust library for comparing versions. It supports some versioning styles(not only for X.Y.Z).

Example

example.rs

use vercomp::{Stage, Version};

fn main() {
    // Version.number is the number of the version. It supports "==", "!=", ">=", ">", "<=" and "<".
    let version_1 = Version::new("1.2.3");
    let version_2 = Version::new("1-2-3");
    if version_1.number == version_2.number {
        println!("version_1 equals version_2.");
    }
    let version_3 = Version::new("1/2/3");
    let version_4 = Version::new("1~2");
    if version_3.number > version_4.number {
        println!("version_3 is greater than version_4.");
    }
    let version_5 = Version::new("1:2");
    let version_6 = Version::new("1;2;3");
    if version_5.number < version_6.number {
        println!("version_5 is less than version_6.");
    }

    // Version.stage is the stage of the version. It only supports "==" and "!=".
    let version_7 = Version::new("1.2.3-Alpha");
    if version_7.stage == Stage::Alpha {
        println!("version_7 is an alpha version.");
    }
    let _version_8 = Version::new("1.2.3-Beta");
    let _version_9 = Version::new("1.2.3");
    // if _version_8 > _version_9 {
        // Compile error
        // Version.stage can not use ">=", ">", "<=" and "<".
    // }
    // "CASE INSENSITIVE"
    // Stage::Alpha   <= Contain alpha 
    // Stage::Beta    <= Contain beta
    // Stage::Dev     <= Contain dev
    // Stage::Nightly <= Contain nightly
    // Stage::Rc      <= Contain rc
    // Stage::Stable  <= others
}
