sparsehash (devel/sparsehash) Add to my watchlist 0

An extremely memory-efficient hash_map implementation. 2 bits/entry overhead! The SparseHash library contains several hash-map implementations, including implementations that optimize for space or speed. These hashtable implementations are similar in API to SGI's hash_map class, but with different performance characteristics. It's easy to replace hash_map by sparse_hash_map or dense_hash_map in C++ code.
