perf: BTreeMap: make `range().count()` more efficient #190

dragoljub-djuric · 2024-02-07T13:19:50Z

Problem:
BTreeMap::Iterator::count() implicitly uses BTreeMap::Iterator::next() which in some cases loads the map entry's value non-lazy.

Solution:
Explicitly reimplement BTreeMap::Iterator::count() so it does not load the value.

@ielashi I can add a benchmark to compare it with the previous implementation, but I am not sure that is important. WDYT?

It is absolutely important :) How else will we know that our change has improved anything?
