Error Handling in Rust

I’ve been doing some programming in Rust recently. First was a flake generator and then the second is a rudimentary implementation of the ls command (dir to Windows people) – I submitted a pull request to uutils/coreutils: a replacement for the UNIX coreutils suite of software. Error handling plays a big role in both of these chunks of…
