Function repeat_with 

pub const fn repeat_with<T, F>(f: F) -> RepeatWith<F>
where
    F: Fn(usize) -> T,

Initializes a slice by calling a closure for each element.

RepeatWith allows you to initialize a slice where each element is produced by calling a closure with the element’s index. This provides a flexible way to create complex slice initializations.

Examples

Creating an array of indices:

use placid::prelude::*;

let mut uninit = uninit!([usize; 5]);
let owned = uninit.write(init::repeat_with(|i| i * 2));
assert_eq!(&*owned, &[0, 2, 4, 6, 8]);
