GetStreamList gets the raw http response when requesting all public streams.

func (*Bot) GetStreams 

func (b *Bot) GetStreams() ([]string, error)

GetStreams returns a list of all public streams

func (*Bot) Init 

func (b *Bot) Init() *Bot

PrivateMessage sends a message to the users in the message email slice.

func (*Bot) RawRegisterEvents

func (b *Bot) Unreact(e EventMessage, emoji string) (*http.Response, error)

Unreact removes an emoji reaction from an EventMessage.

func (*Bot) Unsubscribe 

func (b *Bot) Unsubscribe(streams []string) (*http.Response, error)

Unsubscribe will remove the bot from the given streams. If no streams are given, nothing will happen and the function will error.

}

func (*Queue) EventsCallback 

func (q *Queue) EventsCallback(fn func(EventMessage, error)) func()

EventsCallback will repeatedly call the provided callback function with the output of continual queue.GetEvents calls. It returns a function which can be called to end the calls.

It will end early if it receives an UnauthorizedError, or an unknown error. Note, it will never return a HeartbeatError.

func (*Queue) EventsChan 

func (q *Queue) EventsChan() (chan EventMessage, func())

func (*Queue) GetEvents 

func (q *Queue) GetEvents() ([]EventMessage, error)

GetEvents is a blocking call that waits for and parses a list of EventMessages. There will usually only be one EventMessage returned. When a heartbeat is returned, GetEvents will return a HeartbeatError. When an http status code above 400 is returned, one of a BackoffError, UnauthorizedError, or UnknownError will be returned.

func (*Queue) ParseEventMessages 

func (q *Queue) ParseEventMessages(rawEventResponse []byte) ([]EventMessage, error)

func (*Queue) RawGetEvents 

func (q *Queue) RawGetEvents() (*http.Response, error)

RawGetEvents is a blocking call that receives a response containing a list of events (a.k.a. received messages) since the last message id in the queue.

type StreamJSON 

type StreamJSON struct {
	Msg     string `json:"msg"`
	Streams []struct {
		StreamID    int    `json:"stream_id"`
