Macro input_macro::input

macro_rules! input {
    () => { ... };
    ($($arg:tt)*) => { ... };
}

Displays the formatted prompt to the standard output then reads the next line (CR or CRLF) from the standard input, and returns it as a String.

Panics

Panics if writing to std::io::stdout() fails, or reading from std::io::stdin() fails.

Examples

let name: String = input!("What's your name? ");
let age: i64 = input!("How old are you today {name}? ").parse().unwrap();
println!(
    "In hexadecimal, thats {}{:x}!",
    if age < 0 { "-" } else { "" }, age.abs(),
);
