Function pinned_init::init_array_from_fn

pub fn init_array_from_fn<I, const N: usize, T, E>(
    make_init: impl FnMut(usize) -> I
) -> impl Init<[T; N], E>
where
    I: Init<T, E>,

Initializes an array by initializing each element via the provided initializer.

Examples

use pinned_init::init_array_from_fn;
let array: Box<[usize; 1_000]> = Box::init(init_array_from_fn(|i| i)).unwrap();
assert_eq!(array.len(), 1_000);
