rgba VS Termion

Starting work on a new GBA emulator! Currently just working on decoding ARM instructions...what a strange ISA. I've done the CPU and memory system of a NES emulator in Rust before and that went mostly without a hitch, so I'm hoping the same can be said for this project :)

This is an example from the Termion crate:

There are plenty of terminal UI libraries that are actually nice to work with. For Python, there's Textual and PyTermGUI. For Rust, there's ratatui and Cursive (or, if you want something a bit lower level, crosster or termion). For Go, there's bubbletea.

But let's say I want to write to Termion's raw terminal: stdout().into_raw_mode().unwrap();

And I implemented it for a TermWriter struct (Note: DetectCursorPos comes from the Termion crate):

The following code stores the user input and cursor position in a raw terminal (using Termion):

That being said, termion has already handle this for us (an example).

I'm trying to recreate the Backspace functionality with Termion in raw mode. Right now, it works as expected if I'm deleting the last character. But If I move to the left with the Left arrow, then delete a character, the characters on the right of the cursor won't move to the left.

Termion crate (https://crates.io/crates/termion), and very careful observation of a rust error. Hope your friend finds it useful ;)

If you just need basic printing and limited input then I'd choose either crossterm or termion. If you want a full tui, then tui-rs is really good.
