2019-03-24Rollup merge of #59328 - koalatux:iter-nth-back, r=scottmcmkennytm-0/+3
Implement specialized nth_back() for Box and Windows. Hi there, this is my first pull request to rust :-) I started implementing some specializations for DoubleEndedIterator::nth_back() and these are the first two. The problem has been discussed in #54054 and nth_back() is tracked in #56995. I'm stuck with the next implementation so I though I do a PR for the ones I'm confident with to get some feedback.

Clarify guarantees for `Box` allocation This basically says `Box` does the obvious things for its allocations. See also: https://users.rust-lang.org/t/alloc-crate-guarantees/24981 This may require a T-libs FCP? Not sure. r? @sfackler

fix Box::into_unique effecitvely transmuting to a raw ptr Miri/Stacked Borrows treat `Box` specially: they assert that it is unique, and tag it appropriately. However, currently, `Box::into_inner` is not aware of that and returns a raw pointer (wrapped in a `Unique`) that carries the same tag as the box, meaning it carries a `Uniq` tag. This leads to all sorts of problems when people use the raw pointer they get out of the `Unique` type. In the future, it'd be interesting to make `Unique` also carry some kind of uniqueness. In that case, something like this would instead be needed whenever a raw pointer is extracted from a `Unique`. However, that is out-of-scope for the current version of Stacked Borrows. So until then, this changes `into_unique` to perform a proper reference-to-raw-ptr-cast, which clears the tag.

2018-12-24Rollup merge of #55470 - daniellimws:box-from-docs, r=CentrilMazdak Farrokhzad-0/+54
box: Add documentation for `From` impls This is a part of #51430. A brief description of the behaviour and examples are added to the documentation. I am not sure what sort of examples to put for the `From` for `Pin` as my [code](https://play.rust-lang.org/?version=nightly&mode=debug&edition=2015&gist=97c908f44e41c9faeffec5b61d72a03e) doesn't even manage to compile using the nightly build. Somehow I feel that I missed out something so do let me know if more information is needed in the documentation or any of the examples require change.

2018-12-20Stabilize `Rc`, `Arc` and `Pin` as method receiversMichael Hewson-1/+6
This lets you write methods using `self: Rc<Self>`, `self: Arc<Self>`, `self: Pin<&mut Self>`, `self: Pin<Box<Self>`, and other combinations involving `Pin` and another stdlib receiver type, without needing the `arbitrary_self_types`. Other user-created receiver types can be used, but they still require the feature flag to use. This is implemented by introducing a new trait, `Receiver`, which the method receiver's type must implement if the `arbitrary_self_types` feature is not enabled. To keep composed receiver types such as `&Arc<Self>` unstable, the receiver type is also required to implement `Deref<Target=Self>` when the feature flag is not enabled. This lets you use `self: Rc<Self>` and `self: Arc<Self>` in stable Rust, which was not allowed previously. It was agreed that they would be stabilized in #55786. `self: Pin<&Self>` and other pinned receiver types do not require the `arbitrary_self_types` feature, but they cannot be used on stable because `Pin` still requires the `pin` feature.

2018-11-01Replace CoerceSized trait with DispatchFromDynMichael Hewson-3/+3
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.

This will make receiver types like `Rc<Self>` and `Pin<&mut Self>` object-safe.
