Overview ¶

Types ¶
type Group ¶
type Group[K comparable, V any] struct { // contains filtered or unexported fields }
Group represents a class of work and forms a namespace in which units of work can be executed with duplicate suppression.
func (*Group[K, V]) Do ¶
func (g *Group[K, V]) Do(ctx context.Context, key K, fn func(context.Context) (V, error)) (V, error)
Do executes and returns the results of the given function, making sure that only one execution is in-flight for a given key at a time. If a duplicate comes in, the duplicate caller waits for the original to complete and receives the same results.
