2018-06-17Auto merge of #51466 - joshlf:ref-split, r=dtolnaybors-19/+185
Add Ref/RefMut map_split method As proposed [here](https://internals.rust-lang.org/t/make-refcell-support-slice-splitting/7707). TLDR: Add a `map_split` method that allows multiple `RefMut`s to exist simultaneously so long as they refer to non-overlapping regions of the original `RefCell`. This is useful for things like the slice `split_at_mut` method.

[futures] add a few blanket impls to std these were defined in the futures crate, but with the core definitions moving to std these would need to move too.

add some docs to `From` conversions This adds a helpful document to the bool → int* conversions as well as to the lossless integer conversions. One of #51430 down, some more to go.

2018-06-09Auto merge of #51441 - bstrie:sizeof128, r=dtolnaybors-0/+2
Document size_of for 128-bit integers We might want to consider separately documenting the alignment of primitives, rather than just their size, since 128-bit integers, unlike all other primitives, have an alignment that is not identical to their size (size_of is 16, align_of is 8)

2018-06-08Rollup merge of #51396 - SimonSapin:option-nonzero-layout, r=SimonSapinMark Rousskov-2/+2
Make the size of Option<NonZero*> a documented guarantee. Closes #49137, the tracking issue for `NonZero*`, as this was the last remaining open question. Note that `ptr::NonNull<T>` already documents a similar guarantee.

2018-06-06Auto merge of #51263 - cramertj:futures-in-core, r=aturonbors-0/+611
Add Future and task system to the standard library This adds preliminary versions of the `std::future` and `std::task` modules in order to unblock development of async/await (https://github.com/rust-lang/rust/issues/50547). These shouldn't be considered as final forms of these libraries-- design questions about the libraries should be left on https://github.com/rust-lang/rfcs/pull/2418. Once that RFC (or a successor) is merged, these APIs will be adjusted as necessary. r? @aturon

const fn integer operations A follow up to #51171 Fixes #51267 Makes a lot of the integer methods (`swap_bytes`, `count_ones` etc) `const fn`s. See #51267 for a discussion about why this is wanted and the solution used.

2018-06-02Rollup merge of #51226 - gnzlbg:nonzero_align, r=SimonSapinMark Simulacrum-37/+43
Make Layout's align a NonZeroUsize This PR makes the `Layout`'s align field a `NonZeroUsize` since it cannot ever be zero, not even while building a `Layout`. It also contains some drive-by minor cleanups over the docs and the code, like updating the documented error types, or using the `size()` and `align()` methods instead of accessing the fields directly (the latter was required for the `NonZeroUsize` change anyways). r? @SimonSapin cc @Amanieu
