Macro catch_input::input

macro_rules! input {
    ($x:tt) => { ... };
    ($x:expr) => { ... };
}

Macro that returns a trimmed String containing the user input from standard input. You may pass an argument to be used as a prompt, you may use a FnOnce or a type with the [Display] trait implemented.

Example

let input_a = input!("InputA => ");
let input_b = input!(|| { print!("InputB => "); });
 
assert!(input_a, String::from("Hello"))
assert!(input_b, String::from("World"))
 
/*
$ cargo run
InputA => Hello
InputB => World
*/
