Remove `array_vec.rs`.

2018-09-18T06:29:55+00:00

`SparseBitSet` is the only remaining user of `ArrayVec`. This commit switches it to using `SmallVec`, and removes `array_vec.rs`. Why the switch? Although `SparseBitSet` is size-limited and doesn't need the ability to spill to the heap, `SmallVec` has many more features than `ArrayVec`. In particular, it's now possible to keep `SparseBitSet`'s elements in sorted order, which gives in-order iteration, which is a requirement for the next commit.

Replace usages of ptr::offset with ptr::{add,sub}.

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.~~

Replace manual iter exhaust with for_each(drop).

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.

Rename std::ptr::Shared to NonNull

2018-01-20T09:55:16+00:00

`Shared` is now a deprecated `type` alias. CC https://github.com/rust-lang/rust/issues/27730#issuecomment-352800629
