Function wit_deps::lock

pub async fn lock(
    at: Option<impl AsRef<Path>>,
    manifest: impl AsRef<str>,
    lock: Option<impl AsRef<str>>,
    deps: impl AsRef<Path>,
) -> Result<Option<String>>

Given a TOML-encoded manifest and optional TOML-encoded lock, ensures that the path pointed to by deps is in sync with the manifest and lock. This is a potentially destructive operation! Returns a TOML-encoded lock if the lock passed to this function was either None or out-of-sync.
