I don't know the current state of go package management but I do know the equivalent Go project cited Rust's package manager Cargo as a good reference for developing their own. You forget Rust's standard library is quite minimalist and you get to sample competing libraries which often use interchangeable interfaces. In particular there are several crates (libraries) which make handling CLI arguments convenient.

If your code is stateful the typestate pattern is particularly easy to write in Rust - http://cliffle.com/blog/rust-typestate/

I've never heard of the TypeState Pattern, thanks for the link and it even got me interested in getting to know more about Rust. Thanks a bunch!
