Crate eprompt

Here is a cool example with enums!

 use eprompt::*;
 use std::fmt::Display;

 #[derive(Debug)]
 enum Choices {
     Opt1(i32),
     Opt2(&'static str),
     Opt3,
 }

 impl Display for Choices {
     fn fmt(&self, fmt: &mut std::fmt::Formatter) -> Result<(), std::fmt::Error> {
         match *self {
             Self::Opt1(x) => write!(fmt, "{} of Option 1", x),
             Self::Opt2(x) => write!(fmt, "Option 2 is {}", x),
             Self::Opt3 => write!(fmt, "Mystery option 3"),
         }
     }
 }

 fn main() -> Result<(), std::io::Error> {
     for choice in multi_select("Make a selection",
         &[Choices::Opt1(69), Choices::Opt2("A Brand new pony"), Choices::Opt3]
     )?.map(|x| x.1) {
         match choice {
             Choices::Opt1(x) => todo!("Do something with option 1"),
             Choices::Opt2(x) => todo!("Do something with option 2"),
     }
     
     Ok(())
 }
