type WaitMap ¶

type WaitMap struct {
	sync.Mutex
	// contains filtered or unexported fields
}

WaitMap is a key-value store that enables not only setting and getting values from a map, but also waiting until value for a key becomes available. Important: Since this implementation is tied pretty closely to how it will be used, (as an internal package), it has the peculiar behavior of only the first `Set` setting the value. Subsequent `Sets()` are recorded, but don't change the returned value.

func New() *WaitMap

func (w *WaitMap) Get(key string) (any, bool)

func (w *WaitMap) Set(key string, value any)

func (w *WaitMap) Wait(key string) any

func (w *WaitMap) WaitFor(ctx context.Context, key string) (any, bool)
