@hackage bytestring-trie0.1.1

An efficient finite map from (byte)strings to values.

The implementation is based on /big-endian patricia trees/, like Data.IntMap. We first trie on the elements of Data.ByteString and then trie on the big-endian bit representation of those elements. Patricia trees have efficient algorithms for union and other merging operations, but they're also quick for lookups and insertions.
