layout_of: `T: Thin` implies `sizeof(&T) == sizeof(usize)` Use the `<T as Pointee>::Metadata` associated type to calculate the layout of a pointee's metadata, instead of hard-coding rules about certain types. Maybe this approach is overkill -- we could instead hard-code this approach as a fallback, with the matching on `Slice`/`Dynamic`/etc. happening first Fixes this issue here https://github.com/rust-lang/rust/pull/104338#issuecomment-1312595844 .. But is also useful with transmutes, for example, given the UI test I added below. |
