Description:
efficient packed Unicode text type for Haskell; profiling libraries
This is a Haskell time and space-efficient implementation of Unicode text using packed Word16 arrays. Suitable for performance critical use, both in terms of large data quantities and high speed. . It supports many basic string operations and has some substring search tools. . This package provides a library for the Haskell programming language, compiled for profiling.
