Module documentation for 0.10.6.0

ByteString: Fast, Packed Strings of Bytes

Build Status

This library provides the Data.ByteString module – strict and lazy byte arrays manipulable as strings – providing very time/space-efficient string and IO operations.

For very large data requirements, or constraints on heap size, Data.ByteString.Lazy is provided, a lazy list of bytestring chunks. Efficient processing of multi-gigabyte data can be achieved this way.

The library also provides Data.ByteString.Builder for efficient construction of ByteString values from smaller pieces during binary serialization.

Requirements:

  • Cabal 1.10 or greater
  • cabal-install
  • GHC 6.12 or greater

Building:

cabal install

You can run the testsuite as follows:

cabal test

Authors

ByteString was derived from the GHC PackedString library, originally written by Bryan O’Sullivan, and then by Simon Marlow. It was adapted and greatly extended for darcs by David Roundy and others. Don Stewart and Duncan Coutts cleaned up and further extended the implementation and added the .Lazy code. Simon Meier contributed the Builder feature.
