loop

Rust provides a loop keyword to indicate an infinite loop.

The break statement can be used to exit a loop at anytime, whereas the
continue statement can be used to skip the rest of the iteration and start a
new one.

  1. fn main() {
  2.     let mut count = 0u32;
  4.     println!("Let's count until infinity!");
  6.     // Infinite loop
  7.     loop {
  8.         count += 1;
  10.         if count == 3 {
  11.             println!("three");
  13.             // Skip the rest of this iteration
  14.             continue;
  15.         }
  17.         println!("{}", count);
  19.         if count == 5 {
  20.             println!("OK, that's enough");
  22.             // Exit this loop
  23.             break;
  24.         }
  25.     }
  26. }
