Make `pointer::byte_offset_from` more generic As suggested by https://github.com/rust-lang/rust/issues/96283#issuecomment-1288792955 (cc ````@scottmcm),```` make `pointer::byte_offset_from` work on pointers of different types. `byte_offset_from` really doesn't care about pointer types, so this is totally fine and, for example, allows patterns like this: ```rust ptr::addr_of!(x.b).byte_offset_from(ptr::addr_of!(x)) ``` The only possible downside is that this removes the `T` == `U` hint to inference, but I don't think this matter much. I don't think there are a lot of cases where you'd want to use `byte_offset_from` with a pointer of unbounded type (and in such cases you can just specify the type). ````@rustbot```` label +T-libs-api |
