I'm an indie game development from Serbia. And yes, I'm shamelessly promoting my own open source project...

As stated in the title, it's a library of data structures for constant time insertion, erasure, lookup, and fastest possible iteration. These data structures I needed on many occasions while writing both engine and gameplay code. I couldn't find any open source implementation online, so I decided to implement them myself.

You can look at the code here : https://github.com/im95able/Rea
