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 ¶
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.
