Functions

func MinDuration

func MinDuration(candidates ...*duration.Duration) (exp time.Duration)

MinDuration selects the smallest duration that is > 0 from a set of duration.Duration protobufs.

If none of the supplied Durations are > 0, 0 will be returned.

func WithServices

func WithServices(c context.Context, s Services) context.Context

WithServices installs the supplied Services instance into a Context.

Types

type ProdService

type ProdService struct {
}

ProdService is an instance-global configuration for production Coordinator services. A zero-value struct should be used.

It can be installed via middleware using its Base method. This also fulfills the publisher ClientFactory interface.

func (*ProdService) Base

func (svc *ProdService) Base(c *router.Context, next router.Handler)

Base is Middleware used by Coordinator services.

It installs a production Services instance into the Context.

type ProjectBoundMessage

type ProjectBoundMessage interface {
	// GetMessageProject returns the Project to which this message is bound.
	GetMessageProject() string
}

ProjectBoundMessage describes an object that is bound to a Project namespace.

This is intended to be implemented by project-bound protobufs.

type Services

type Services interface {
	coordinator.ConfigProvider
}

Services is a set of support services used by AppEngine Classic Coordinator endpoints.

Each instance is valid for a single request, but can be re-used throughout that request. This is advised, as the Services instance may optionally cache values.

Services methods are goroutine-safe.

func GetServices

func GetServices(c context.Context) Services

GetServices gets the Services instance installed in the supplied Context.

If no Services has been installed, it will panic.
