Phantom Protocol Public API

Transport session facade for the SDK.

• session::PhantomSession — Client-first transport session (all targets)
• stream::PhantomStream — Multiplexed reliable stream (all targets)
• listener::PhantomListener — Server socket listener (native only)
• tcp_transport::TcpSessionTransport — Length-prefixed framing over TCP (native only)

On wasm32-unknown-unknown (browser) targets the TCP-based building blocks are absent; use WebSocketLeg as the SessionTransport implementation. On wasm32-wasi* targets with --features wasi-leg, use WasiLeg (paired with WasiRuntime) for a TCP-shaped transport over WASI Preview 2 sockets.

Modules

listener

session

Client-First Transport Session

stream

tcp_transport

Length-prefixed SessionTransport over tokio::net::TcpStream.

udp_listener

PhantomUDP server listener: one bound UdpSocket, a central demux task routing datagrams by the 8-byte connection-ID into per-session channels, and a decoupled accept queue mirroring PhantomListener. Rust-only in Phase 1 (no UniFFI surface yet).

udp_transport

SessionTransport impls over raw UDP (PhantomUDP). UdpClientTransport is an unconnected-socket client (it send_tos a tracked server address and recv_froms any source, so it can hear — and later follow — a server that migrates to a new address); UdpServerTransport is a per-session shim fed by the listener demux that can migrate its own send socket. Both add / strip the outer [flags][cid] envelope exactly as TcpSessionTransport adds / strips its 4-byte length prefix, so run_data_pump / run_client_handshake / drive_server_handshake are reused.
