type Group Uses

type Group 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) Do Uses

func (g *Group) Do(key string, fn func() (interface{}, error)) (interface{}, 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.
