2018-12-07Unique/NonNull::from: make sure we convert to raw pointers ASAPRalf Jung-4/+4
By going through a shared reference, we share the destination as read-only, meaning we can read but not write with the raw pointers
2018-12-07Rollup merge of #56250 - dwijnand:ptr-hash, r=alexcrichtonkennytm-0/+30
Introduce ptr::hash for references The RHS is what I used, which wasn't as convenient as `ptr::eq`, so I wondered: should `ptr::hash` exist? My first Rust PR, so I'm going to need some guidance. :)

2018-12-01Auto merge of #56165 - RalfJung:drop-glue-type, r=eddyb,nikomatsakisbors-2/+12
drop glue takes in mutable references, it should reflect that in its type When drop glue begins, it should retag, like all functions taking references do. But to do that, it needs to take the reference at a proper type: `&mut T`, not `*mut T`. Failing to retag can mean that the memory the reference points to remains frozen, and `EscapeToRaw` on a frozen location is a NOP, meaning later mutations cause a Stacked Borrows violation. Cc @nikomatsakis @Gankro because Stacked Borrows Cc @eddyb for the changes to miri argument passing (the intention is to allow passing `*mut [u8]` when `&mut [u8]` is expected and vice versa)

Minor standard library constification This PR makes some bits of the standard library into `const fn`s. I've tried to be as aggressive as I possibly could in the constification.

2018-11-01Replace CoerceSized trait with DispatchFromDynMichael Hewson-4/+4
Rename `CoerceSized` to `DispatchFromDyn`, and reverse the direction so that, for example, you write ``` impl<T: Unsize<U>, U> DispatchFromDyn<*const U> for *const T {} ``` instead of ``` impl<T: Unsize<U>, U> DispatchFromDyn<*const T> for *const U {} ``` this way the trait is really just a subset of `CoerceUnsized`. The checks in object_safety.rs are updated for the new trait, and some documentation and method names in there are updated for the new trait name — e.g. `receiver_is_coercible` is now called `receiver_is_dispatchable`. Since the trait now works in the opposite direction, some code had to updated here for that too. I did not update the error messages for invalid `CoerceSized` (now `DispatchFromDyn`) implementations, except to find/replace `CoerceSized` with `DispatchFromDyn`. Will ask for suggestions in the PR thread.
2018-11-01Add CoerceSized impls throughout libstdMichael Hewson-1/+7
This will make receiver types like `Rc<Self>` and `Pin<&mut Self>` object-safe.

2018-10-14remove unnecessary emphasis in doc commentJan Niehusmann-2/+2
During review of the previous commit, @joshtriplett noticed that the emphasis on 'the same' is unnecessary. For consistency, remove it on the offset() functions, as well.
2018-10-14clarify pointer add/sub function safety concernsJan Niehusmann-4/+4
Ralf Jung made the same changes to the offset functions' documentation in commit fb089156. As add/sub just call offset, the same limitation applies here, as well. Removed emphasis on review request by @joshtriplett

2018-09-24Auto merge of #53783 - RalfJung:ptr-docs, r=alexcrichtonbors-513/+541
Rewrite docs for pointer methods This takes over https://github.com/rust-lang/rust/pull/51016 by @ecstatic-morse. They did most of the work, I just did some editing. However, I realized one problem: This updates the docs for the "free functions" in `core::ptr`, but it does not update the copies of these docs for the inherent methods of the `*const T` and `*mut T` types. These getting out-of-sync is certainly bad, but I also don't feel like copying all this stuff around. Instead, we should remove this redundancy. Any good ideas?
