type EventsClient

type EventsClient interface {
	// Publish an event to a topic.
	//
	// The event will be packed into a timestamp envelope with the namespace
	// introspected from the context. The envelope will then be dispatched.
	Publish(ctx context.Context, in *PublishRequest, opts ...grpc.CallOption) (*types.Empty, error)
	// Forward sends an event that has already been packaged into an envelope
	// with a timestamp and namespace.
	//
	// This is useful if earlier timestamping is required or when forwarding on
	// behalf of another component, namespace or publisher.
	Forward(ctx context.Context, in *ForwardRequest, opts ...grpc.CallOption) (*types.Empty, error)
	// Subscribe to a stream of events, possibly returning only that match any
	// of the provided filters.
	//
	// Unlike many other methods in containerd, subscribers will get messages
	// from all namespaces unless otherwise specified. If this is not desired,
	// a filter can be provided in the format 'namespace==<namespace>' to
	// restrict the received events.
	Subscribe(ctx context.Context, in *SubscribeRequest, opts ...grpc.CallOption) (Events_SubscribeClient, error)
}

EventsClient is the client API for Events service.
