LIVE: Learning Rust Error Handling: Results, Panics & Custom Errors

I feel personally victimized by a Rust compiler error. Today we’re working through the Error Primer and Tasks in the Rust quest, trying to make these tests pass without losing our minds.

Using JetBrains Academy's Learn Rust course https://link.bashbunni.dev/EQdftG (not sponsored, just using it :) )

Inside the stream:
- Rust Tasks: Solving Result matching and custom error challenges.
- Tooling: Using RustRover for interactive learning (and why I still use Emacs/Doom Emacs).
- Gear Talk: A breakdown of my Keychron setup and linear vs. magnetic switches.
