Types ¶
type Service ¶
type Service interface {
// Start spawns any goroutines required by the service.
Start()
// Stop terminates all goroutines belonging to the service,
// blocking until they are all terminated.
Stop() error
// Returns error if the service is not considered healthy.
Status() error
}
Service is a struct that can be registered into a ServiceRegistry for easy dependency management.
type ServiceRegistry ¶
type ServiceRegistry struct {
// contains filtered or unexported fields
}
ServiceRegistry provides a useful pattern for managing services. It allows for ease of dependency management and ensures services dependent on others use the same references in memory.
func NewServiceRegistry ¶
func NewServiceRegistry() *ServiceRegistry
NewServiceRegistry starts a registry instance for convenience
func (*ServiceRegistry) FetchService ¶
func (s *ServiceRegistry) FetchService(service interface{}) error
FetchService takes in a struct pointer and sets the value of that pointer to a service currently stored in the service registry. This ensures the input argument is set to the right pointer that refers to the originally registered service.
func (*ServiceRegistry) RegisterService ¶
func (s *ServiceRegistry) RegisterService(service Service) error
RegisterService appends a service constructor function to the service registry.
func (*ServiceRegistry) StartAll ¶
func (s *ServiceRegistry) StartAll()
StartAll initialized each service in order of registration.
func (*ServiceRegistry) Statuses ¶
func (s *ServiceRegistry) Statuses() map[reflect.Type]error
Statuses returns a map of Service type -> error. The map will be populated with the results of each service.Status() method call.
func (*ServiceRegistry) StopAll ¶
func (s *ServiceRegistry) StopAll()
StopAll ends every service in reverse order of registration, logging a panic if any of them fail to stop.
