This library is a work in progress
It currently does not support server push and assumes correct input from servers -- it is not robust in the face of server errors or invalid data being sent.
Only HTTP/2 over TLS is supported, which requires SWI-Prolog 7.7.19 or greater for TLS-ALPN support.
It is available as an SWI pack and can be installed by running ?- pack_install(http2_client).
Contributions extremely welcome
Requires the list_util and delay packs.
Uses the reif library.
