// Static and dynamic tables for the HPACK decoder. See:
// http://httpwg.org/specs/rfc7541.html#indexing.tables

// Note that the Lookup methods return nullptr if the requested index was not
// found. This should be treated as a COMPRESSION error according to the HTTP/2
// spec, which is a connection level protocol error (i.e. the connection must
// be terminated). See these sections in the two RFCs:
// http://httpwg.org/specs/rfc7541.html#indexed.header.representation
// http://httpwg.org/specs/rfc7541.html#index.address.space
// http://httpwg.org/specs/rfc7540.html#HeaderBlock
