Text codecs
encode :: MonadThrow m => Codec -> Conduit Text m ByteStringSource
Convert text into bytes, using the provided codec. If the codec is not capable of representing an input character, an exception will be thrown.
Since 0.3.0
decode :: MonadThrow m => Codec -> Conduit ByteString m TextSource
Convert bytes into text, using the provided codec. If the codec is not capable of decoding an input byte sequence, an exception will be thrown.
Since 0.3.0
linesBounded :: MonadThrow m => Int -> Conduit Text m TextSource
Variant of the lines function with an integer parameter. The text length of any emitted line never exceeds the value of the paramater. Whenever this is about to happen a LengthExceeded exception is thrown. This function should be used instead of the lines function whenever we are dealing with user input (e.g. a file upload) because we can't be sure that user input won't have extraordinarily large lines which would require large amounts of memory if consumed.
data TextException Source
Since 0.3.0
decodeUtf8 :: MonadThrow m => Conduit ByteString m TextSource
Decode a stream of UTF8-encoded bytes into a stream of text, throwing an exception on invalid input.
Since 1.0.15
encodeUtf8 :: Monad m => Conduit Text m ByteStringSource
Encode a stream of text into a stream of bytes.
Since 1.0.15
