Rust Fundamental Libraries Worth Trying
#1 clap
Building CLI tools in Rust is a natural fit - just look at ripgrep and Rust 's own Cargo . Superfast startup times, small binary sizes, input safe code, runtime safe binaries, cross compiling to just about any architecture you might want.To start building CLI tools, clap is a great CLI library, and it's so good that I don't see any reason to have alternatives that are common in a dozen other languages. In fact, if you want to try Rust , I suggest you take a look at rustup and try this library to see what it can bring you.

#2 serde
Like clap , serde is a feature-rich, high-performance general-purpose serialization library. In fact, thinking about Java and .net , I can't remember a serialization library that does so well in all aspects - ergonomics and performance.Instead of trying to read and write files yourself, write the datatypes first and let serde do all the work. As a bonus, you can mix and match data formats ( YAML, JSON ) after all operations are done.
#3 reqwest
Reqwest follows the gold standard of HTTP Client libraries such as request , superagent and requests and applies them perfectly to Rust . It's my go-to library for HTTP Clients and is fully featured.
