Woo! Just completed #Satisfactory without nuclear power. And it only took 360 hours. I'm sure everyone can agree that's time well spent.

(Now I'm inevitably going to learn that someone has speedrun the entire thing in three hours flat.)

Is there some way to have a #Rust HashMap find (or create if the key is new) the entry for a given key, then release the reference to that key?

I called entry(key) and held the given Entry, hoping that (lookup now finished) the borrow would be released, but that's not the case.

I'm trying to avoid heap allocation when grabbing map entries that have already been created. (Obivously heap allocation is needed to create a held key in the first place, but after that it seems wasteful.)
