Integer encoding with a write buffer.

Encoding integer with a temporary buffer whose size is 4096. No prefix is set.

>>> BS.unpack <$> encodeInteger 5 10[10]>>> BS.unpack <$> encodeInteger 5 1337[31,154,10]>>> BS.unpack <$> encodeInteger 8 42[42]

Integer decoding with a read buffer. The first argument is N of prefix.

Integer decoding. The first argument is N of prefix.

>>> decodeInteger 5 10 $ BS.empty10>>> decodeInteger 5 31 $ BS.pack [154,10]1337>>> decodeInteger 8 42 $ BS.empty42

String encoding. The algorithm based on copy avoidance and selection of better result of huffman or raw.

String encoding (7+) with a temporary buffer whose size is 4096.

Converting a header list of the http-types style to TokenHeaderList and ValueTable.

String decoding with Huffman decoder.

Converting to '[Header]'.

• Headers are decoded as is.

• DecodeError would be thrown if the HPACK format is broken.

• BufferOverrun will be thrown if the temporary buffer for Huffman decoding is too small.

Converting to TokenHeaderList and ValueTable.

• Multiple values of Cookie: are concatenated.

• If a pseudo header appears multiple times, IllegalHeaderName is thrown.

• If unknown pseudo headers appear, IllegalHeaderName is thrown.

• If pseudo headers are found after normal headers, IllegalHeaderName is thrown.

• If a header key contains capital letters, IllegalHeaderName is thrown.

• If the number of header fields is too large, TooLargeHeader is thrown

• DecodeError would be thrown if the HPACK format is broken.

• BufferOverrun will be thrown if the temporary buffer for Huffman decoding is too small.
