2021-01-16Rollup merge of #80681 - ChrisJefferson:logic-error-doc, r=m-ou-seMara Bos-1/+4
Clarify what the effects of a 'logic error' are This clarifies what a 'logic error' is (which is a term used to describe what happens if you put things in a hash table or btree and then use something like a refcell to break the internal ordering). This tries to be as vague as possible, as we don't really want to promise what happens, except "bad things, but not UB". This was discussed in #80657

2020-09-21Auto merge of #75974 - SkiFire13:peekmut-opt-sift, r=LukasKalbertodtbors-2/+4
Avoid useless sift_down when std::collections::binary_heap::PeekMut is never mutably dereferenced If `deref_mut` is never called then it's not possible for the element to be mutated without internal mutability, meaning there's no need to call `sift_down`. This could be a little improvement in cases where you want to mutate the biggest element of the heap only if it satisfies a certain predicate that needs only read access to the element.
