#[repr(C)]
pub union AlignAs<T: Copy, A: Copy> {
// some fields omitted
}
Wrap an object of type T to give it the alignment requirements of an object of type A.
This has a similar effect to #[repr(align(...))], but is parameterized to support the creation
of structures that are generic over alignment.
Example:
extern crate alignas;
use alignas::AlignAs;
use std::{mem, slice};
let mut buffer: AlignAs<_, u64> = AlignAs::new([0u8; 64]);
buffer[3..18].copy_from_slice(b"some input here");
let mut ints = [0u64; 8];
let ptr = &buffer as *const _ as *const u64;
ints.copy_from_slice(unsafe { slice::from_raw_parts(ptr, 8) });
Put the given T object into an aligned location
