feature request: allow packed types #1704
Description
Would it be possible to add support for packed types? Types appear to be unpacked right now (which is fine in itself) but it blocks interop with C APIs like epoll_wait.
Example: on x86_64, (0u32, 0u64) is 12 bytes when packed and 16 bytes when unpacked.

While I do think we should support this in the language, you could probably hack around the problem with unsafe pointers.
Add failing test.

I'm ok taking a patch to add
packedas a prefix type operator to a record, vector or tuple type. It'll be a bit of a pain to support but does seem to be part of the world we live in.auto merge of #5816 : dbaupp/rust/rustc-packed-v2, r=nikomatsakis
