Move some alloc crate top-level items to a new alloc::collections module

2018-06-29T12:01:33+00:00

This matches std::collections

rename RangeBounds::start() -> start_bound() rename RangeBounds::end() -> end_bound()

Auto merge of #48945 - clarcharr:iter_exhaust, r=Kimundi

Replace manual iterator exhaust with for_each(drop) This originally added a dedicated method, `Iterator::exhaust`, and has since been replaced with `for_each(drop)`, which is more idiomatic. This is just shorthand for `for _ in &mut self {}` or `while let Some(_) = self.next() {}`. This states the intent a lot more clearly than the identical code: run the iterator to completion. At least personally, my eyes tend to gloss over `for _ in &mut self {}` without fully paying attention to what it does; having a `Drop` implementation akin to: ~~`for _ in &mut self {}; unsafe { free(self.ptr); }`~~ Is not as clear as: `self.exhaust(); unsafe { free(self.ptr); }` ~~Additionally, I've seen debate over whether `while let Some(_) = self.next() {}` or `for _ in &mut self {}` is more clear, whereas `self.exhaust()` is clearer than both.~~

Cleanup liballoc use statements

2018-04-13T23:43:13+00:00

Some modules were still using the deprecated `allocator` module, use the `alloc` module instead. Some modules were using `super` while it's not needed. Some modules were more or less ordering them, and other not, so the latter have been modified to match the others.

Replace manual iter exhaust with for_each(drop).

Remove all unstable placement features

2018-04-03T09:02:34+00:00

Closes #22181, #27779

Move RangeArguments to {core::std}::ops and rename to RangeBounds

2018-03-29T11:12:49+00:00

These unstable items are deprecated: * The `std::collections::range::RangeArgument` reexport * The `std::collections::range` module.

Move alloc::Bound to {core,std}::ops

2018-03-29T11:12:49+00:00

The stable reexport `std::collections::Bound` is now deprecated. Another deprecated reexport could be added in `alloc`, but that crate is unstable.
