Description

Synopsis

IOData & IODataMode type

data IOData #

Represents either textual or binary data passed via I/O functions which support binary/text mode

Since: 2.2.0

Constructors

IODataText String

How Text gets encoded is usually locale-dependent.

IODataBinary ByteString

Raw binary which gets read/written in binary mode.

Instances

NFData IOData # 

Methods

rnf :: IOData -> () #

data IODataMode #

Constructors

IODataModeText 
IODataModeBinary 

null :: IOData -> Bool #

Test whether IOData is empty

Since: 2.2.0

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.

Since: 2.2.0
