func (*Client) SetMaxMessageSize

func (c *Client) SetMaxMessageSize(s int64)

SetMaxMessageSize sets the maximum size to allow for messages

type Socket

type Socket struct {
	// contains filtered or unexported fields
}

Socket manages sending messages over a socket to many subscribed clients

func NewSocket

func NewSocket(addr string, log logging.Logger) *Socket
