favorite Rust libs

clap: I consider this one of the killer libs in the Rust ecosystem... there is good taste in terms of design, it is comprehensive, and it has a very pleasant way of using it, the derive API.

serde: This one seems to get even more praise (compared to clap), and is perhaps as good as anything in other language ecosystems in its domain, especially with its derive API (as is the case with clap).

anyhow: The most popular error crate in the ecosystem, it offers very easy error handling, and also comes with some nice conveniences, like bail!, ensure!, and Context.
