std::string_view imr::mold::PacketBuilder::Config::session

MoldUDP64 Session, Must be 10 characters.

MTU

std::size_t imr::mold::PacketBuilder::Config::MTU {1472}

MTU for packet, default is ethernet MTU (1500 bytes) - IP/UDP headers (28 bytes).

min_message_size

std::size_t imr::mold::PacketBuilder::Config::min_message_size {PacketBuilder::min_message_size}

Smallest possible message size (including 2-byte length prefix); defaults to 14 (TotalView-ITCH 5.0).

Configurable in case a future TotalView version introduces smaller messages.

Used to size the iovecs vector for the worst case packet (MTU / min_message_size), i.e. a packet filled entirely with minimum-size messages.
