Crate standard_version 

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));

Structs

BumpSummary

Summary of analysed commits for display purposes.

Enums

BumpLevel

The level of version bump to apply.

Functions

apply_bump

Apply a bump level to a semver version, returning the new version.

apply_prerelease

Apply a pre-release bump. If the current version already has a pre-release tag matching tag, the numeric suffix is incremented. Otherwise, .0 is appended to the bumped version.

determine_bump

Analyse a list of conventional commits and return the highest applicable bump level.

replace_version_in_toml

Replace the version value in a TOML string’s [package] section while preserving formatting.

summarise

Summarise a list of conventional commits for display purposes.
