Types

type CodeError

type CodeError int

func (CodeError) Error

func (err CodeError) Error() string

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)) (v interface{}, 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) DoChan

func (g *Group) DoChan(key string, fn func() (interface{}, error)) <-chan Result

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) Forget

func (g *Group) 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 Jar

type Jar struct {
	PsList cookiejar.PublicSuffixList `json:"pslist"`

	// mu locks the remaining fields.
	Mu sync.Mutex `json:"mu"`

	// entries is a set of entries, keyed by their eTLD+1 and subkeyed by
	// their name/domain/path.
	Entries map[string]map[string]entry `json:"entries"`

	// nextSeqNum is the next sequence number assigned to a new cookie
	// created SetCookies.
	NextSeqNum uint64 `json:"nextseqnum"`
}

type Result

type Result struct {
	Val    interface{}
	Err    error
	Shared bool
}

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