Yes, according to the archived Rust implmentation[1] which in turn refers you to either clap[2] or structopt[3]. Other implmentations does not mention this but those I looked at had not been touched for years. Either very stable or unmaintained. Unfortunately the latter according to the Rust crate. The dotNet implmentation had a very small version bump in the dependencies but the rest of the project does not seem to have been touched the past 2 years.
