Struct cobalt::ConnectionID

pub struct ConnectionID(pub u32);

Representation of a random ID for connection identification purposes.

Used to uniquely* identify the reliable connections. The ID is send with every packet and allows to support multiple connections behind NAT. It also reduces the chance of connection drop attacks it also and helps with cases where NAT re-assigns local UDP ports which would cause purely address based packet identification mechanisms to break down.

* Since the ID is random integer, there is of course a always a chance for two connections to end up with the same ID, in that case - due to conflicting ack sequences and message data - both connections will get dropped shortly.
