standard-version 0.11.12

//! Semantic version bump calculation from conventional commits.
//!
//! Computes the next version from a list of parsed conventional commits and
//! bump rules. Also provides the [`VersionFile`] trait for ecosystem-specific
//! version file detection and updating, with built-in support for
//! `Cargo.toml` via [`CargoVersionFile`], `pyproject.toml` via
//! [`PyprojectVersionFile`], `package.json` via [`JsonVersionFile`],
//! `deno.json`/`deno.jsonc` via [`DenoVersionFile`], `pubspec.yaml` via
//! [`PubspecVersionFile`], `gradle.properties` via [`GradleVersionFile`],
//! and plain `VERSION` files via [`PlainVersionFile`].
//!
//! # 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
//! - [`update_version_files`] — discover and update version files at a repo root
//!
//! # 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));
//! ```
