read-stdin is a small set of functions I wrote once I got sick of writing code for handling user input in a terminal so I decided to publish it online for anyone to enjoy.
You can use read_stdin to ask the user for input. This function will return a Result that will be Ok if the user enters something that successfuly parses into a generic type of your choice, and Err if it fails parsing.
use read_stdin::read_stdin;
let Ok(n) = read_stdin::<i32>() else {
println!("You entered an incorrect data type!");
return;
};
println!("You entered: {}", n)You can also use read_stdin_util_ok if you wish to annoy the user until their data parses correctly.
use read_stdin::read_stdin_until_ok;
let n = read_stdin_until_ok::<i32>();
println!("You entered: {}", n)
