This makes
AlignedVec
generic over alignments by using a markertrait AlignedByteChunk
impl
ed for types with the same alignment and size (e.x.Align64<[u8; 64]>
. Since#[repr(align(N))]
is not a const generic, const generics couldn't be used for this, but this works nicely. We check thatmem::size_of::<C>() == mem::align_of::<C>()
inAlignedVec
's constructors to ensureAlignedByteChunk
isimpl
ed on valid types. Thus, I also ensured that theAlignedVec
s were actually constructed, not transmuted throughunsafe { mem::zeroed() }
.
