nomad-protocol 0.2.0

//! NOMAD Protocol - Transport Layer
//!
//! This module implements the transport layer of the NOMAD protocol as specified
//! in 2-TRANSPORT.md. It provides:
//!
//! - **Frame encoding/decoding**: [`DataFrame`], [`CloseFrame`], and wire format handling
//! - **Connection state machine**: [`ConnectionState`] with lifecycle management
//! - **RTT estimation**: [`RttEstimator`] implementing RFC 6298
//! - **Frame pacing**: [`FramePacer`] to prevent buffer bloat
//! - **Connection migration**: [`MigrationState`] for seamless IP roaming
//! - **Async sockets**: [`NomadSocket`] wrapper for tokio UDP
//!
//! # Architecture
//!
//! The transport layer sits between the security layer and the sync layer.
//! It handles frame framing, timing, and connection management while remaining
//! agnostic to the encrypted payload contents.
