ioWithFileBytes :: Text -> (ByteString -> IO a) -> IO a Source #
Reads contents of a specified file as a lazy ByteString (with streaming)
and provides it to the specified callback
Throws IOWithFileBytesException if specified file cannot be read
Arguments:
path :: Text: path to filefun :: (Data.ByteString.Lazy.ByteString -> IO a): callback to process the file data
Return value: Result of the callback invocation
ioWithFileText :: Text -> (Text -> IO a) -> IO a Source #
Reads contents of a specified file as a lazy Text (with streaming)
and provides it to the specified callback
File contents are decoded as UTF-8
Throws IOWithFileBytesException if specified file cannot be read
Arguments:
path :: Text: path to filefun :: (Data.Text.Lazy.Text -> IO a): callback to process the file data
Return value: Result of the callback invocation
