Repeat string with integer multiplication

Question

Is there an easy way to do the following (from Python) in Rust?

>>> print ("Repeat" * 4) RepeatRepeatRepeatRepeat

I'm starting to learn the language, and it seems String doesn't override Mul, and I can't find any discussion anywhere on a compact way of doing this (other than a map or loop).

Rust 1.16+

str::repeat is now available:

fn main() {     let repeated = "Repeat".repeat(4);     println!("{}", repeated); } 

Rust 1.0+

You can use iter::repeat:

use std::iter;  fn main() {     let repeated: String = iter::repeat("Repeat").take(4).collect();     println!("{}", repeated); } 

This also has the benefit of being more generic — it creates an infinitely repeating iterator of any type that is cloneable.
