cargo-update 命令

常用示例

说明

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.
