	Oldest protocol version the server accepts.
std::uint32_t	max = kProtocolVersion
	Newest protocol version the server accepts.
std::vector< std::string >	capabilities
	Optional envelope kinds the server honours, beyond those every server of this protocol version does (e.g. kCapabilityCancel).

Member Data Documentation

min

std::uint32_t morph::wire::ProtocolRange::min = kProtocolVersion

Oldest protocol version the server accepts.

Definition at line 186 of file wire.hpp.

max

std::uint32_t morph::wire::ProtocolRange::max = kProtocolVersion

Newest protocol version the server accepts.

Definition at line 189 of file wire.hpp.

capabilities

std::vector<std::string> morph::wire::ProtocolRange::capabilities

Optional envelope kinds the server honours, beyond those every server of this protocol version does (e.g. kCapabilityCancel).

Additive: a reply from a server that predates the list has no such key, and decodes to an empty list — "nothing optional is supported".
