Description:
mutable hash tables -- profiling libraries; profiling libraries
This package provides a couple of different implementations of mutable hash tables in the ST monad, as well as a typeclass abstracting their common operations, and a set of wrappers to use the hash tables in the IO monad. . There are three hash table implementations: . * Data.HashTable.ST.Basic contains a basic open-addressing hash table using linear probing as the collision strategy. This should currently be the fastest available hash table implementation for lookups, although it has a higher memory overhead than others. * Data.HashTable.ST.Cuckoo contains an implementation of "cuckoo hashing". Cuckoo hashing has worst-case O(1) lookups and performs well even when the table is highly loaded. * Data.HashTable.ST.Linear contains a linear hash table, which trades some insert and lookup performance for higher space efficiency and much shorter delays when expanding the table. . This package provides a library for the Haskell programming language, compiled for profiling. See http://www.haskell.org/ for more information on Haskell.
