rtm

type Client struct {
	// OpenURL fetches a fresh wss:// URL (rtm.connect). RTM URLs are single-use and must be
	// connected within ~30s, so every (re)connection asks for a new one.
	OpenURL func(ctx context.Context) (string, error)
	// Dial opens the websocket. Defaults to coder/websocket; injectable for tests.
	Dial func(ctx context.Context, url string) (conn, error)
	// Log receives connection-lifecycle notes (connected, reconnecting). Never event data.
	Log io.Writer
	// Header carries credential headers on the WebSocket handshake. For a browser-session
	// token this holds `Cookie: d=<xoxd>`, which the RTM gateway validates on the UPGRADE —
	// the URL ticket alone answers invalid_auth for xoxc tokens.
	Header http.Header
	// PingInterval is how often to send an application-level RTM ping to keep the
	// connection alive. Zero uses the 30s default; negative disables pings (tests).
	PingInterval time.Duration
	// contains filtered or unexported fields
