Rust TUI Tutorial: Ratatui, Multithreading, and Responsiveness

#rustlang #tui #userinterface Ratatui is a popular Rust crate for building terminal user interfaces (TUIs). We explore how Ratatui interacts with the terminal, set up a simple user interface and take a deep dive into responsiveness. We'll opt for an efficient and modular design by implementing an event driven architecture for updating progress of a background computation as well as handling user input. Thanks to @littlesandra87 for hinting me at this great TUI crate, I had quite a bit of fun with it throughout the last few days :) I had a bit of a cold while recording the video, so my voice sounds a bit off at times. I hope you don't mind too much.
