Introduction
In this tutorial we learn how to install libghc-hashtables-prof on Ubuntu 18.04.
What is libghc-hashtables-prof
libghc-hashtables-prof is:
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.
There are three methods to install libghc-hashtables-prof on Ubuntu 18.04. We can use apt-get, apt and aptitude. In the following sections we will describe each method. You can choose one of them.
