The Rust standard library endeavours to do as little as possible and even then, there have been cases where something was added and later folks realised it was a mistake. For example std::sync::mpsc. No one is recommended to use it (crossbeam crate is the preferred alternative). Getopt used to be in the standard library (clap crate is better). Obviously mpsc shouldn't be in the standard library but it can't be removed without breaking backwards compat - essentially stagnating. So a suboptimal solution remains. Rust's solution is to have an official "cookbook" that shows how to use these crates to accomplish common tasks. For example, crossbeam is featured here - https://rust-lang-nursery.github.io/rust-cookbook/concurrency/threads.html https://rust-lang-nursery.github.io/rust-cookbook/concurrenc.... In case a better library comes along, it's simple to update the cookbook. In this scenario's no one's programs are broken and the standard library remains slim. Do you disagree with the cookbook approach?
