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.
