2020-05-19Auto merge of #71447 - cuviper:unsized_cow, r=dtolnaybors-0/+1
impl From<Cow> for Box, Rc, and Arc These forward `Borrowed`/`Owned` values to existing `From` impls. - `Box<T>` is a fundamental type, so it would be a breaking change to add a blanket impl. Therefore, `From<Cow>` is only implemented for `[T]`, `str`, `CStr`, `OsStr`, and `Path`. - For `Rc<T>` and `Arc<T>`, `From<Cow>` is implemented for everything that implements `From` the borrowed and owned types separately.

2019-11-13Auto merge of #65637 - ssomers:master, r=scottmcmbors-0/+1
proposal for BTreeMap/Set min/max, #62924 - Which pair of names: #62924 lists the existing possibilities min/max, first/last, (EDIT) front/back, peek(/peek_back?). Iterators have next/next_back or next/last. I'm slightly in favour of first/last because min/max might suggest they search over the entire map, and front/back pretends they are only about position. - Return key only instead of pair like iterator does? - If not, then keep the _key_value suffix? ~~Also provide variant with mutable value? But there is no such variant for get_key_value.~~ - Look for and upgrade more usages of `.iter().next()` and such in the libraries? I only upgraded the ones I contributed myself, all very recently.
2019-10-31Auto merge of #65091 - sekineh:into-iter-sorted, r=KodrAusbors-0/+2
Implement ordered/sorted iterators on BinaryHeap as per #59278 I've implemented the ordered version of iterator on BinaryHeap as per #59278. # Added methods: * `.into_iter_sorted()` * like `.into_iter()`; but returns elements in heap order * `.drain_sorted()` * like `.drain()`; but returns elements in heap order * It's a bit _lazy_; elements are removed on drop. (Edit: it’s similar to vec::Drain) For `DrainSorted` struct, I implemented `Drop` trait following @scottmcm 's [suggestion](https://github.com/rust-lang/rust/issues/59278#issuecomment-537306925) # ~TODO~ DONE * ~I think I need to add more tests other than doctest.~ # **Notes:** * we renamed `_ordered` to `_sorted`, because the latter is more common in rust libs. (as suggested by @KodrAus )

2018-11-11std: Delete the `alloc_system` crateAlex Crichton-2/+0
This commit deletes the `alloc_system` crate from the standard distribution. This unstable crate is no longer needed in the modern stable global allocator world, but rather its functionality is folded directly into the standard library. The standard library was already the only stable location to access this crate, and as a result this should not affect any stable code.

Incorporate a stray test `liballoc/repeat-generic-slice.rs` doesn't seem to be tested (I think it was intended to be placed in `run-pass`). This PR incorporates the test into `liballoc/tests`.
