Types

type Service

type Service interface {
	// Shutdown initiates shutdown
	Shutdown()
	// RegisterCallback registers functions to be called on shutdown and before
	// the shutdown channel is closed. A callback error will propagate to the
	// context error
	RegisterCallback(func(context.Context) error)
}

Service is used to facilitate shutdown by through callback registration and shutdown initiation

func WithShutdown

func WithShutdown(ctx context.Context) (context.Context, Service)

WithShutdown returns a context which is similar to a cancel context, but with callbacks which can propagate to the context error. Unlike a cancel context, the shutdown context cannot be canceled from the parent context. However, future child contexes will be canceled upon shutdown.
