I love browsing crates.io and blessed.rs for interesting and useful crates to experiment with. What are your favorite?
I’m especially interested in those simple ones that do one thing and do it will, like uuid, tempfile, and notify.

I mean serde is – in my understanding – the most useful crate out there. It does exactly one thing and that very well.
Dtolney, the author for serde, has a stupid amount of libraries that fit this.
Other than serde, he owns syn, thiserror, anyhow, and async-trait.
He’s practically the Atlas of the Rust ecosystem.
Here are some I found and used in my own code:
- itertools
- regex
- anyhow and thiserror (error handling)
- indoc (indented/formatted multi line string literals)
- strum (various derive macros for enums)
- petgraph (for working with general graphs)
- winnow is a great (and fast) parser combinator library.
- bpaf, clap and xflags are three different command line argument parser libraries. Which one to use depends on the needs of the project and if you need to match the behaviour of an existing non-rust program (as I needed to in one case)
