Types ¶

type Group ¶

type Group[T 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[T]) Do ¶

func (g *Group[T]) Do(key string, fn func() (T, error)) (v T, err error, shared bool)

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.

func (*Group[T]) DoChan ¶

func (g *Group[T]) DoChan(key string, fn func() (T, error)) <-chan Result[T]

DoChan is like Do but returns a channel that will receive the results when they are ready.

The returned channel will not be closed.

func (*Group[T]) Forget ¶

func (g *Group[T]) Forget(key string)

Forget tells the singleflight to forget about a key. Future calls to Do for this key will call the function rather than waiting for an earlier call to complete.

type Result ¶

type Result[T any] struct {
	Val    T
	Err    error
	Shared bool
}

Result holds the results of Do, so they can be passed on a channel.
