Instances

NFData IOData

Defined in Distribution.Utils.IOData

Methods

rnf :: IOData -> ()

data IODataMode

Constructors

IODataModeText

IODataModeBinary

null :: IOData -> Bool

Test whether IOData is empty

hGetContents :: Handle -> IODataMode -> IO IOData

IOData Wrapper for hGetContents

Note: This operation uses lazy I/O. Use NFData to force all data to be read and consequently the internal file handle to be closed.

Since: 2.2.0

hPutContents :: Handle -> IOData -> IO ()

IOData Wrapper for hPutStr and hClose

This is the dual operation ot ioDataHGetContents, and consequently the handle is closed with hClose.
