Struct Connection 

pub struct Connection { /* private fields */ }

Low-level WebSocket connection handle.

Wraps a split tokio-tungstenite stream (sink + source) and provides simple send/recv methods for raw frames. This type is not meant to be used directly by application code — the session layer manages it.

Implementations

impl Connection

pub async fn connect(config: &TransportConfig) -> Result<Self, ConnectError>

Establish a WebSocket connection (does not send the setup message).

pub async fn send_text(&mut self, json: &str) -> Result<(), SendError>

Send a text frame (typically a serialised JSON message).

pub async fn send_binary(&mut self, data: &[u8]) -> Result<(), SendError>

Send a binary frame.

pub async fn recv(&mut self) -> Result<RawFrame, RecvError>

Receive the next meaningful frame, skipping ping/pong control frames.

pub async fn close(self) -> Result<(), SendError>

Gracefully close the connection by sending a close frame.
