Yuki Okushi 56ae3fb2f0 Rollup merge of #81706 - SkiFire13:document-binaryheap-unsafe, r=Mark-Simulacrum ... Document BinaryHeap unsafe functions `BinaryHeap` contains some private safe functions but that are actually unsafe to call. This PR marks them `unsafe` and documents all the `unsafe` function calls inside them. While doing this I might also have found a bug: some "SAFETY" comments in `sift_down_range` and `sift_down_to_bottom` are valid only if you assume that `child` doesn't overflow. However it may overflow if `end > isize::MAX` which can be true for ZSTs (but I think only for them). I guess the easiest fix would be to skip any sifting if `mem::size_of::<T> == 0`. Probably conflicts with #81127 but solving the eventual merge conflict should be pretty easy.		2021-02-21 15:26:40 +09:00
