Package singleflight provides a duplicate function call suppression mechanism.
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.
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.
Package singleflight imports 1 packages (graph) and is imported by 26 packages. Updated 2019-11-15. Refresh now. Tools for package owners.
