cargo update [options]

cargo update updates dependencies recorded in Cargo.lock to the latest versions compatible with the version requirements specified in Cargo.toml. If Cargo.lock does not exist, it is created. Without the `-p` flag, all dependencies are updated.
When used with `-p`, only the specified package is updated conservatively. The `--precise` flag can pin a package to an exact version. The lockfile ensures reproducible builds across environments; running `cargo update` is the standard way to pull in bug fixes and minor updates from dependencies while respecting semver constraints.

Cargo.lock is auto-maintained. Update when you want newer compatible versions. Lockfile ensures reproducible builds.
