`core` lacks a stable version of `transmute`

[Lokathor]

We obviously have std::mem::transmute, but for core we only have

• core::intrinsics::transmute: unstable / feature gated
• core::mem::transmute_copy: which is actually more dangerous than transmute because it's missing the "before and after have the same size" check.

So can we get core::mem::transmute?

[jonas-schievink]

It's there, it's just a reexport of the intrinsic: https://doc.rust-lang.org/core/mem/index.html#reexports

[jonas-schievink]

(which is stable, so I don't know what you're referring to)

[Lokathor]

Oh, well then the docs are messed up because if you search for transmute it doesn't list out core::mem::transmute as being available.

[Lokathor]

On the Discord I was referred to this PR: #57848

but that's from back in January, so it's confusing why the search still doesn't work right

https://doc.rust-lang.org/std/index.html?search=transmute

@Lokathor I see core::mem::transmute in your link.

(Note that the search index is defined in a .js file that can be cached. If you still don't see it, try hard-refreshing.)

[Lokathor]

alright, just some confusion then
