I consider rand, clap, tokio, serde, and hyper, among others, to be canonical Rust libraries. There may be alternatives, but a new person might be wondering "how do I generate a random number in Rust" and not want to roll their own RNG or find another library. And that's not to say you have to use any of those in any particular project, just that they are the main options for achieving their particular functionality.
