Use transmute_unchecked and make the types explicit in query type e…

…rasure

This doesn't really change anything, but makes the code a bit more explicit/readable.

Use consisntent style of size_of in query type erasure
b3d5025 
All other impls replace type generics with `()` (or a type implementing the necessery traits)
and lifetimes with `'static`, do the same for those impls.

Why this change given that transmute_unchecked is unstable?

cjgillot commented Oct 4, 2023

For the first commit: all the types here are Copy. Adding the types are generic arguments to transmute_copy should be enough, as transmute_unchecked does not assert size equality.
For the second commit: ok.

@Zoxc @cjgillot I've used transmute_unchecked because I think it better describes the operation we want (transmute without checking the size), rather than transmute_copy. Yes, transmute_copy is also fine because of the Copy bound, but it's not always easy to notice that (tbh at thirst I thought the code is unsound).

So yeah. I'd prefer to use transmute_uncheked here because it's clearer. Lmk if you disagree, I can change it back to transmute_copy. @rustbot review
