Network.HPACK

Converting '[Header]' to the HPACK format. This function has overhead of allocating/freeing a temporary buffer. BufferOverrun will be thrown if the temporary buffer is too small.

Converting the HPACK format 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.

A full HTTP header field with the name and value separated.

E.g. "Content-Length: 28" parsed into a Header would turn into ("Content-Length", "28")

Retrieve the original string-like value.

Retrieve the case folded string-like value. (Also see foldCase).

Make the given string-like value case insensitive.

Converting TokenHeaderList to the HPACK format directly in the buffer.

When calling this function for a new TokenHeaderList, 4th argument must be True.

The return value is a pair of leftover TokenHeaderList and how many bytes are filled in the buffer. If the leftover is empty, the encoding is finished. Otherwise, this function should be called with it again. 4th argument must be False.

4th argument is relating to dynamic table size update. If True and the limit is set by setLimitForEncoding, dynamic table size update is generated at the beginning of the HPACK format.

Converting the HPACK format 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.

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

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

Type for dynamic table.

Default dynamic table size. The value is 4,096 bytes: an array has 128 entries.

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

An array to get FieldValue quickly. getHeaderValue should be used. Internally, the key is tokenIx.
