pub const unsafe fn transmute<Src, Dst>(src: Src) -> Dst...For Vec, this means that both the size and alignment of the inner types have to match. Other containers might rely on the size of the type, alignment, or even the TypeId, in which case transmuting wouldn't be possible at all without violating the container invariants.

primitive fn...Note that FFI requires additional care to ensure that the ABI for both sides of the call match. The exact requirements are not currently documented.
Safety
Plain function pointers are obtained by casting either plain functions, or closures that don't capture an environment:
