Struct UNINIT_ARRAY

pub struct UNINIT_ARRAY<T, const N: usize>(/* private fields */);

Generic constant for an uninitialized [MaybeUninit<T>; N]. Requires Rust 1.51.0.

Features

This requires the “rust_1_51” feature, which requires Rust 1.51.0.

Example

use konst::maybe_uninit::UNINIT_ARRAY;

use std::mem::{self, MaybeUninit};

const INITS: [[u8; 2]; 2] = {
    let mut uninits = [UNINIT_ARRAY::<u8, 2>::V; 2];

    uninits[0] = [MaybeUninit::new(3), MaybeUninit::new(5)];
    uninits[1] = [MaybeUninit::new(8), MaybeUninit::new(13)];

    unsafe{ mem::transmute(uninits) }
};

assert_eq!(INITS, [[3, 5], [8, 13]]);

Implementations

impl<T, const N: usize> UNINIT_ARRAY<T, N>

pub const V: [MaybeUninit<T>; N]

The value that this constructs.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
