2020-03-26Overhaul of the `AllocRef` trait to match allocator-wg's latest consensTim Diekmann-1043/+0
2020-03-22Auto merge of #69079 - CAD97:layout-of-ptr, r=RalfJungbors-0/+36
Allow calculating the layout behind a pointer There was some discussion around allowing this previously. This does make the requirement for raw pointers to have valid metadata exposed as part of the std API (as a safety invariant, not validity invariant), though I think this is not strictly necessarily required as of current. cc @rust-lang/wg-unsafe-code-guidelines Naming is hard; I picked the best "obvious" name I could come up with. If it's agreed that this is actually a desired API surface, I'll file a tracking issue and update the attributes.

2020-02-12Rollup merge of #69027 - TimDiekmann:zeroed-alloc, r=AmanieuYuki Okushi-0/+137
Add missing `_zeroed` varants to `AllocRef` The majority of the allocator wg has decided to add the missing `_zeroed` variants to `AllocRef`: > these should be added since they can be efficiently implemented with the `mremap` system call on Linux. `mremap` allows you to move/grow/shrink a memory mapping, and any new pages added for growth are guaranteed to be zeroed. > > If `AllocRef` does not have these methods then the user will have to manually write zeroes to the added memory since the API makes no guarantees on their contents. For the full discussion please see https://github.com/rust-lang/wg-allocators/issues/14. This PR provides default implementations for `realloc_zeroed`, `alloc_excess_zeroed`, `realloc_excess_zeroed`, and `grow_in_place_zeroed`. r? @Amanieu

2020-02-01Remove `Alloc` in favor of `AllocRef`Tim Diekmann-7/+0
`AllocRef` was reexported as `Alloc` in order to not break toolstate in the week before the next stable release.

2020-01-20Added minor clarification to specification of realloc.Matthew Parkinson-1/+2
The `layout` for the returned allocation of a `realloc` is only implicitly specified. This change makes it explicit.
