  Description     : fast, dense hashmap and hashset header-only library

A fast & densely stored hashmap and hashset based on robin-hood backward
shift deletion for C++17 and later.

The classes ankerl::unordered_dense::map and
ankerl::unordered_dense::set are (almost) drop-in replacements of
std::unordered_map and std::unordered_set.  While they don't have as
strong iterator / reference stability guarantees, they are typically
much faster.

Additionally, there are ankerl::unordered_dense::segmented_map and
ankerl::unordered_dense::segmented_set with lower peak memory usage, and
stable references (iterators are NOT stable) on insert.


This package is a dependency to github.com/shader-slang/slang which I
intend to open an ITP once my current packaging state is more refined.
