Variables

var ErrSkipped = errors.New("skipped performing")

ErrSkipped is returned when an edge skips performing because the operation would be a no-op.

Types

type PromotionEdge

type PromotionEdge[R core.Resource] struct {
	// contains filtered or unexported fields
}

PromotionEdge is a type edge implementation which supports promoting from a source phase to a destination phase.

func Promotes

func Promotes[R core.Resource](from typed.Phase[R], to typed.UpdatablePhase[R]) *PromotionEdge[R]

func (*PromotionEdge[R]) CanPerform

func (s *PromotionEdge[R]) CanPerform(ctx context.Context) (bool, error)

func (*PromotionEdge[R]) From

func (s *PromotionEdge[R]) From() core.Descriptor

func (*PromotionEdge[R]) Kind

func (s *PromotionEdge[R]) Kind() string

func (*PromotionEdge[R]) Perform

func (s *PromotionEdge[R]) Perform(ctx context.Context) (r *core.Result, err error)

Perform causes a promotion from a dependent to a target phase. The phase fetches both its current resource state, and that of the promotion source phase. If the resources differ, then the phase updates its source to match the promoted version.

func (*PromotionEdge[R]) To

func (s *PromotionEdge[R]) To() core.Descriptor
