Abstraction and base class for packet-based protocols.
PacketPeer is an abstraction and base class for packet-based protocols (such as UDP). It provides an API for sending and receiving packets both as raw data or variables. This makes it easy to transfer data over a protocol, without having to encode data as low level bytes or having to worry about network ordering.
Return the number of packets currently available in the ring-buffer.
Get a raw packet.
Return the error state of the last packet received (via [method get_packet] and [method get_var]).
Get a Variant.
Send a raw packet.
Send a Variant as a packet.
