Functions

func Write

func Write(ctx context.Context, conn *websocket.Conn, r io.Reader, sender string) error

Write the contents of the reader along the WebSocket connection. This is done by sending each WebSocket message as a gRPC message frame. Each message frame is length-prefixed message, where the prefix is 5 bytes. gRPC request format is specified here: https://github.com/grpc/grpc/blob/master/doc/PROTOCOL-HTTP2.md.
