Modules

error

Error enum declaration for server-side WebSocket errors.

handshake

Module containing simple convenience handshake functions such as greeting()

Result module encapsulating Result enum used by the WebSocketServer

Structs

WebSocketServer

WebSocketServer that provides the main websocket connection and message processing loop that delivers messages to the installed WebSocketHandler trait.

Enums

Message

An enum representing the various forms of a WebSocket message.

Traits

WebSocketHandler

WebSocketHandler trait that represents the WebSocket processor functionality. This trait is supplied to the WebSocket which subsequently invokes it’s functions during websocket connection and messages. The trait can override with_handshake() method to enable invocation of the handshake() method upon receipt of the first valid websocket message from the incoming connection.

WebSocketServerTrait

Base WebSocketServer trait allows the WebSocketServer<T> struct to be retained by the trait reference by castring it to the trait as follows:

Type Definitions

WebSocketReceiver

WebSocket stream receiver for receiving tungstenite::Message. This stream object must have a mutable reference and can not be cloned.

WebSocketSender

WebSocket stream sender for dispatching tungstenite::Message. This stream object must have a mutable reference and can not be cloned.

WebSocketSink

WebSocketSink tokio::sync::mpsc::UnboundedSender for dispatching messages from within the WebSocketHandler::message. This is an MPSC channel that can be cloned and retained externally for the lifetime of the WebSocket connection.
