Macro bump_into::space_zeroed_aligned

macro_rules! space_zeroed_aligned {
    (size: $size:expr, align: $align:literal $(,)?) => { ... };
}

Creates a zeroed array of one MaybeUninit without allocating on the heap, with the given size and alignment, suitable for taking a slice of to pass into BumpInto::from_slice.

The size will be rounded up to the nearest multiple of the given alignment.

The size must be a const expression of type usize. The alignment must be a power-of-two integer literal.

Example

use bump_into::space_zeroed_aligned;
use core::mem;

let mut space = space_zeroed_aligned!(size: 64, align: 4);
assert_eq!(mem::size_of_val(&space), 64);
assert_eq!(mem::align_of_val(&space), 4);
