WebSocketConn

Struct WebSocketConn 

pub struct WebSocketConn { /* private fields */ }
Available on crate feature websockets only.
Expand description

A struct that represents an specific websocket connection.

This can be thought of as a combination of a async_tungstenite::WebSocketStream and a trillium::Conn, as it contains a combination of their fields and associated functions.

The WebSocketConn implements Stream<Item=Result<Message, Error>>, and can be polled with StreamExt::next

Implementations§
