//! ## RLDP - Reliable Large Datagram Protocol
//!
//! A reliable arbitrary-size datagram protocol built upon the ADNL, called RLDP, is used instead
//! of a TCP-like protocol. This reliable datagram protocol can be employed, for instance,
//! to send RPC queries to remote hosts and receive answers from them.
