/* sort exporteds by: | */
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. The return value shared indicates whether v was given to multiple callers. DoChan is like Do but returns a channel that will receive the results when they are ready. ForgetUnshared tells the singleflight to forget about a key if it is not shared with any other goroutines. Future calls to Do for a forgotten key will call the function rather than waiting for an earlier call to complete. Returns whether the key was forgotten or unknown--that is, whether no other goroutines are waiting for the result.
Result holds the results of Do, so they can be passed on a channel. Err error Shared bool Val any func (*Group).DoChan(key string, fn func() (any, error)) <-chan Result
