I am learning Rust now, in an attempt to redo some Python scripts that run too slow (using threading). I was going to go with C (worked with it for years back in the 90's), until I stumbled upon Rust.

Rust is so easy to install and get up and running on any platform. But I am getting increasingly frustrated with documentation of many crates I try to use which were so easy in Python. For example serde, log4rs, clap (docs are pretty good).

For example, I can not find any way to change the log level in the log4rs implementation at runtime, or how to configure formatters with the yaml file.
