Quickly parse an integer from a string with str::parse, and handle invalid input with unwrapor.

Rust 
let s = "42";
let num: i32 = s.parse().unwrapor(0);
println!("Parsed number: {}", num); let invalid = "hello";
let fallback: i32 = invalid.parse().unwrapor(-1);
println!("Fallback number: {}", fallback);
