Control.Lens.Internal.ByteString

Description

This module spends a lot of time fiddling around with `ByteString` internals to work around http://hackage.haskell.org/trac/ghc/ticket/7556 on older Haskell Platforms and to improve constant and asymptotic factors in our performance.

# Documentation

unpackStrict :: ByteString -> [Word8] #

Unpack a strict `Bytestring`

traversedStrictTree :: IndexedTraversal' Int ByteString Word8 #

Traverse a strict `ByteString` in a relatively balanced fashion, as a balanced tree with biased runs of elements at the leaves.

unpackStrict8 :: ByteString -> String #

Unpack a strict `Bytestring`, pretending the bytes are chars.

traversedStrictTree8 :: IndexedTraversal' Int ByteString Char #

Traverse a strict `ByteString` in a relatively balanced fashion, as a balanced tree with biased runs of elements at the leaves, pretending the bytes are chars.

unpackLazy :: ByteString -> [Word8] #

Unpack a lazy `Bytestring`

traversedLazy :: IndexedTraversal' Int64 ByteString Word8 #

An `IndexedTraversal` of the individual bytes in a lazy `ByteString`

unpackLazy8 :: ByteString -> String #

Unpack a lazy `ByteString` pretending the bytes are chars.

traversedLazy8 :: IndexedTraversal' Int64 ByteString Char #

An `IndexedTraversal` of the individual bytes in a lazy `ByteString` pretending the bytes are chars.
