Rollup merge of #71459 - divergentdave:pointer-offset-0x, r=RalfJung

Dylan-DPC · web-flow · commit ed25ca0efbb1 · 2020-04-24T02:47:37.000+02:00
Add leading 0x to offset in Debug fmt of Pointer Currently the `Debug` format for `Pointer` prints its offset in hexadecimal, for example, `alloc38657819+e2` or `alloc35122748+64`. This PR adds a leading `0x` to the offset, in order to make it apparent that it is indeed a hexadecimal number. This came up during discussion of rust-lang/miri#1354. r? @RalfJung
