inputparser

Takes terminal input in specified format

Instead of

let mut input:String = String::new();
io::stdin().read_line(&mut input).unwrap();
let input:i32=input.trim().parse().unwrap();

why not

let input:i32= inputparser::inti32conv();

and it shows error and doesn't exit till proper input is entered

Usage

[dependencies]
inputparser = "0.1"

Example

fn main() {
  let i = inputparser::inti32conv();
  println!("{}",i);
}
