bors 1a7c203e7f Auto merge of #89123 - the8472:push_in_capacity, r=amanieu ... add Vec::push_within_capacity - fallible, does not allocate This method can serve several purposes. It * is fallible * guarantees that items in Vec aren't moved * allows loops that do `reserve` and `push` separately to avoid pulling in the allocation machinery a second time in the `push` part which should make things easier on the optimizer * eases the path towards `ArrayVec` a bit since - compared to `push()` - there are fewer questions around how it should be implemented I haven't named it `try_push` because that should probably occupy a middle ground that will still try to reserve and only return an error in the unlikely OOM case. resolves #84649		2022-10-09 21:02:33 +00:00
