type CachedGroup ¶

type CachedGroup[T any] struct {
	// CacheError defines if error results should also be cached.
	// It is not safe to change this value after the first call to Do.
	// Context cancellation errors are never cached.
	CacheError bool
	// contains filtered or unexported fields
}

Group is a flightcontrol synchronization group that memoizes the results of a function and returns the cached result if the function is called with the same key. Don't use with long-running groups as the results are cached indefinitely.

func (g *CachedGroup[T]) Do(ctx context.Context, key string, fn func(ctx context.Context) (T, error)) (T, error)
