2018-04-02Use Alloc and Layout from core::heap.Mike Hommey-1/+2
94d1970bba87f2d2893f6e934e4c3f02ed50604d moved the alloc::allocator module to core::heap, moving e.g. Alloc and Layout out of the alloc crate. While alloc::heap reexports them, it's better to use them from where they really come from.
2018-03-29Remove unnecessary use core::hash in liballoc/boxed.rsMike Hommey-2/+2
It' only used for hash::Hasher, but Hasher is also imported.

2018-03-03core: Update stability attributes for FusedIteratorUlrik Sverdrup-1/+1
2018-03-03core: Stabilize FusedIteratorUlrik Sverdrup-1/+1
FusedIterator is a marker trait that promises that the implementing iterator continues to return `None` from `.next()` once it has returned `None` once (and/or `.next_back()`, if implemented). The effects of FusedIterator are already widely available through `.fuse()`, but with stable `FusedIterator`, stable Rust users can implement this trait for their iterators when appropriate.

2018-01-24Auto merge of #47299 - cramertj:unsafe-placer, r=alexcrichtonbors-1/+1
Make core::ops::Place an unsafe trait Consumers of `Place` would reasonably expect that the `pointer` function returns a valid pointer to memory that can actually be written to.

2018-01-20Replace Box::{from,into}_unique with {from,into}_nonnull_rawSimon Sapin-20/+27
Thew `_raw` prefix is included because the fact that `Box`’s ownership semantics are "dissolved" or recreated seem more important than the exact parameter type or return type.

2017-11-23Auto merge of #45881 - Centril:box-leak, r=alexcrichtonbors-0/+53
Add Box::leak<'a>(Box<T>) -> &'a mut T where T: 'a Adds: ```rust impl<T: ?Sized> Box<T> { pub fn leak<'a>(b: Box<T>) -> &'a mut T where T: 'a { unsafe { &mut *Box::into_raw(b) } } } ``` which is useful for when you just want to put some stuff on the heap and then have a reference to it for the remainder of the program. r? @sfackler cc @durka

2017-10-10Auto merge of #44877 - nvzqz:box-conversions, r=alexcrichtonbors-4/+40
Improve raw Box conversions This PR has two goals: - Reduce use of `mem::transmute` in `Box` conversions I understand that `mem::transmute`-ing non `#[repr(C)]` types is implementation-defined behavior. This may not matter within the reference implementation of Rust, but I believe it's important to remain consistent. For example, I noticed that `str::from_utf8_unchecked` went from using `mem::transmute` to using pointer casts. - Make `Box` pointer conversions more straightforward regarding `Unique`

2017-10-06Add missing word in Box::from_unique docsNikolai Vazquez-2/+2
2017-10-06Create Box::from_unique functionNikolai Vazquez-3/+35
Provides a reasonable interface for Box::from_raw implementation. Does not get around the requirement of mem::transmute for converting back and forth between Unique and Box.
2017-10-06Revert to using mem::transmute in Box::from_rawNikolai Vazquez-1/+1
Same reasons as commit 904133e1e28b690e2bbd101b719509aa897539a0.
