Rustacean 🦀

This repo is here to follow my progress learning the Rust programming language.

It contains code for examples and exercises from the Rust Book, split into folders corresponding to chapter numbers. Some bits might correspond to the interactive version of the Rust Book too.

I'm also working through exercises from Rustlings, roughly corresponding to the book order.

I'm writing these in vim (all being well), partially to force myself to not rely on VS Code's autocompletion & linting, and partially to finally memorise vim & tmux's keybindings.
