Semantic version bump calculation from conventional commits.

Pure library — computes the next version from a list of parsed conventional commits and bump rules. No I/O, no git operations.

Main entry points

• [determine_bump] — analyse commits and return the bump level
• [apply_bump] — apply a bump level to a semver version
• [apply_prerelease] — bump with a pre-release tag (e.g. rc.0)
• [replace_version_in_toml] — update the version in a Cargo.toml string

Example

use standard_version::{determine_bump, apply_bump, BumpLevel};

let commits = vec![
    standard_commit::parse("feat: add login").unwrap(),
    standard_commit::parse("fix: handle timeout").unwrap(),
];

let level = determine_bump(&commits).unwrap();
assert_eq!(level, BumpLevel::Minor);

let current = semver::Version::new(1, 2, 3);
let next = apply_bump(&current, level);
assert_eq!(next, semver::Version::new(1, 3, 0));
