Overview ¶

Package idempotency provides a duplicate function call suppression mechanism. It is a lightly modified version of groupcache's singleflight package that does not forget keys until explicitly told to.

Index ¶

type Group
- func (g *Group) Forget(key string)
- func (g *Group) Once(key string, fn func() (interface{}, error)) (interface{}, error)

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) Forget ¶

func (g *Group) Forget(key string)

Forget forgets a key, allowing the next call for the key to execute the function.

func (*Group) Once ¶

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

Once executes and returns the results of the given function, making sure that only one execution for a given key happens until the key is explicitly forgotten. If a duplicate comes in, the duplicate caller waits for the original to complete and receives the same results.
