Description:
Efficient hashing-based container types
It contains efficient hashing-based container types. The containers have been optimized for performance critical use, both in terms of large data quantities and high speed. . The declared cost of each operation is either worst-case or amortized, but remains valid even if structures are shared. . This package provides a library for the Haskell programming language. See http://www.haskell.org/ for more information on Haskell.
