How to get the F1, F2, F3 ... keys in Rust ? 💬

#rust #programming #tutorial #opensource

If you're using a GNU/Linux operating system and want to develop a system that requires the F1, F2, F3, and so on keys as inputs, I recommend reading this short article on how to do it!

First of all, let's add the library that will allow us to interact with keyboard events at a low level. I'm talking about k_board.

cargo add k_board

Let's add the program's logic:

use k_board::{Keyboard, Keys};

fn main() {
    for key in Keyboard::new() {
        match key {
            Keys::F(1) => /*run some function*/,
            Keys::F(5) => /*update screen*/,
            Keys::F(11) => /*full screen*/,
            Keys::Enter => break,
            _ => {}
        }
    }
}
