Stage 2.7: Setup Visual Studio Code
I recommend using Visual Studio Code for developing Rust programs.
Visual Studio Code is a modular editor which can be extended with with useful tools (called extensions) to improve your developing experience for Rust programming.
Besides the official Rust extension there are also extension packs which offers some additional tools often needed for Rust programming, e. g. an extension for TOML files.
I can recommend you an extension pack of my own, which you can find here: Rust Extension Pack.
