#include <bn_unordered_set.h>
template<typename Key, int MaxSize, typename KeyHash, typename KeyEqual>
bn::unordered_set class

std::unordered_set like container with a fixed size buffer.

Template parameters
Key Element type.
MaxSize Maximum number of elements that can be stored.
KeyHash Functor used to calculate the hash of a given key.
KeyEqual Functor used for all key comparisons.

It doesn't throw exceptions. Instead, asserts are used to ensure valid usage.

Unlike std::unordered_set, it doesn't offer pointer stability when moving or erasing elements.
