Function `transmute_unchecked`

unsafe const fn transmute_unchecked<Src, Dst>(src: Src) -> Dst

Like transmute, but even less checked at compile-time: rather than giving an error for size_of::<Src>() != size_of::<Dst>(), it's Undefined Behavior at runtime.

Prefer normal transmute where possible, for the extra checking, since both do exactly the same thing at runtime, if they both compile.

This is not expected to ever be exposed directly to users, rather it may eventually be exposed through some more-constrained API.
