Macro prompt

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

Prints to the standard output. Then reads a line of input.

This is a shorthand for calling print!, read_line, and removing any trailing newlines from the output.

Examples

use io_prompt_prototype::prompt;

let num: u16 = prompt!("What's your favorite number? >").parse()?;
println!("Oh, cool: {}!", num);
