Functions

func NewClient

func NewClient(conn *rpcc.Conn) *domainClient

NewClient returns a client for the BackgroundService domain with the connection set to conn.

Types

type ClearEventsArgs

type ClearEventsArgs struct {
	Service ServiceName `json:"service"` // No description.
}

ClearEventsArgs represents the arguments for ClearEvents in the BackgroundService domain.

func NewClearEventsArgs

func NewClearEventsArgs(service ServiceName) *ClearEventsArgs

NewClearEventsArgs initializes ClearEventsArgs with the required arguments.

type Event

type Event struct {
	Timestamp                   network.TimeSinceEpoch       `json:"timestamp"`                   // Timestamp of the event (in seconds).
	Origin                      string                       `json:"origin"`                      // The origin this event belongs to.
	ServiceWorkerRegistrationID serviceworker.RegistrationID `json:"serviceWorkerRegistrationId"` // The Service Worker ID that initiated the event.
	Service                     ServiceName                  `json:"service"`                     // The Background Service this event belongs to.
	EventName                   string                       `json:"eventName"`                   // A description of the event.
	InstanceID                  string                       `json:"instanceId"`                  // An identifier that groups related events together.
	EventMetadata               []EventMetadata              `json:"eventMetadata"`               // A list of event-specific information.
}

Event

type EventMetadata

type EventMetadata struct {
	Key   string `json:"key"`   // No description.
	Value string `json:"value"` // No description.
}

EventMetadata A key-value pair for additional event information to pass along.

type EventReceivedClient

type EventReceivedClient interface {
	// Recv calls RecvMsg on rpcc.Stream, blocks until the event is
	// triggered, context canceled or connection closed.
	Recv() (*EventReceivedReply, error)
	rpcc.Stream
}

EventReceivedClient is a client for BackgroundServiceEventReceived events. Called with all existing backgroundServiceEvents when enabled, and all new events afterwards if enabled and recording.

type EventReceivedReply

type EventReceivedReply struct {
	BackgroundServiceEvent Event `json:"backgroundServiceEvent"` // No description.
}

EventReceivedReply is the reply for BackgroundServiceEventReceived events.

type RecordingStateChangedClient

type RecordingStateChangedClient interface {
	// Recv calls RecvMsg on rpcc.Stream, blocks until the event is
	// triggered, context canceled or connection closed.
	Recv() (*RecordingStateChangedReply, error)
	rpcc.Stream
}

RecordingStateChangedClient is a client for RecordingStateChanged events. Called when the recording state for the service has been updated.

type RecordingStateChangedReply

type RecordingStateChangedReply struct {
	IsRecording bool        `json:"isRecording"` // No description.
	Service     ServiceName `json:"service"`     // No description.
}

RecordingStateChangedReply is the reply for RecordingStateChanged events.

type ServiceName

type ServiceName string

ServiceName The Background Service that will be associated with the commands/events. Every Background Service operates independently, but they share the same API.

const (
	ServiceNameNotSet          ServiceName = ""
	ServiceNameBackgroundFetch ServiceName = "backgroundFetch"
	ServiceNameBackgroundSync  ServiceName = "backgroundSync"
	ServiceNamePushMessaging   ServiceName = "pushMessaging"
	ServiceNameNotifications   ServiceName = "notifications"
)

ServiceName as enums.

func (ServiceName) String

func (e ServiceName) String() string

func (ServiceName) Valid

func (e ServiceName) Valid() bool

type SetRecordingArgs

type SetRecordingArgs struct {
	ShouldRecord bool        `json:"shouldRecord"` // No description.
	Service      ServiceName `json:"service"`      // No description.
}

SetRecordingArgs represents the arguments for SetRecording in the BackgroundService domain.

func NewSetRecordingArgs

func NewSetRecordingArgs(shouldRecord bool, service ServiceName) *SetRecordingArgs

NewSetRecordingArgs initializes SetRecordingArgs with the required arguments.

type StartObservingArgs

type StartObservingArgs struct {
	Service ServiceName `json:"service"` // No description.
}

StartObservingArgs represents the arguments for StartObserving in the BackgroundService domain.

func NewStartObservingArgs

func NewStartObservingArgs(service ServiceName) *StartObservingArgs

NewStartObservingArgs initializes StartObservingArgs with the required arguments.

type StopObservingArgs

type StopObservingArgs struct {
	Service ServiceName `json:"service"` // No description.
}

StopObservingArgs represents the arguments for StopObserving in the BackgroundService domain.

func NewStopObservingArgs

func NewStopObservingArgs(service ServiceName) *StopObservingArgs

NewStopObservingArgs initializes StopObservingArgs with the required arguments.
