Macro bump_into::space_uninit_aligned

macro_rules! space_uninit_aligned {
    (capacity: $capacity:expr, align: $align:expr $(,)?) => { ... };
}

Creates an uninitialized single MaybeUninit on the stack, with the given capacity and alignment, suitable for passing into BumpInto::from_single.

The alignment given must be suitable for use as the parameter to repr(align), i.e. (as of Rust 1.45.0) a basic integer literal.

Examples

use bump_into::space_uninit_aligned;
use core::mem;

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