Documentation

class Unpack s where Source #

Class of things that can be unpacked into Strings. Kind of the opposite of IsString.

w2c :: Word8 -> Char #

Conversion between Word8 and Char. Should compile to a no-op.

c2w :: Char -> Word8 #

Unsafe conversion between Char and Word8. This is a no-op and silently truncates to 8 bits Chars > '\255'. It is provided as convenience for ByteString construction.

decodeBytes :: ByteString -> Text Source #

Converts Bytes into Text. This uses UTF8, but if there is an error, it pretends it was Latin1. Evil as this is, it tends to Just Work on files where nobody ever wasted a thought on encodings.

encodeBytes :: Text -> ByteString Source #

Converts Text into Bytes. This uses UTF8.

decompressGzip :: ByteString -> ByteString Source #

Decompresses Gzip or Bgzf and passes everything else on. In reality, it simply decompresses Gzip, and when done, looks for another Gzip stream. Since there is a small chance to attempt decompression of an uncompressed stream, the original data is returned in case of an error.
