Function std::array::repeat

pub fn repeat<T, const N: usize>(val: T) -> [T; N]
where
    T: Clone,

🔬This is a nightly-only experimental API. (array_repeat #126695)

Creates an array of type [T; N] by repeatedly cloning a value.

This is the same as [val; N], but it also works for types that do not implement Copy.

The provided value will be used as an element of the resulting array and will be cloned N - 1 times to fill up the rest. If N is zero, the value will be dropped.

Example

Creating muliple copies of a String:

#![feature(array_repeat)]

use std::array;

let string = "Hello there!".to_string();
let strings = array::repeat(string);
assert_eq!(strings, ["Hello there!", "Hello there!"]);
