    Types

    type Group

    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

      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.
