Types

type BufferedRandomIdGenerator

type BufferedRandomIdGenerator struct {
	// contains filtered or unexported fields
}

BufferedRandomIdGenerator is used to fetch random generator ids while avoiding a mutex. The random ids are prefetched ina single goroutine in the background. You have to call close to stop this goroutine.

func NewBufferedRandomIdGenerator

func NewBufferedRandomIdGenerator(idLength int, bufferSize int) *BufferedRandomIdGenerator

NewBufferedRandomIdGenerator instantiates a new generator with the given buffer size. The BufferedRandomIdGenerator has to be closed to avoid leaking the prefetch go routine.

func (*BufferedRandomIdGenerator) Close

func (gen *BufferedRandomIdGenerator) Close() error

Close stops the background prefetch process. Does not error.

func (*BufferedRandomIdGenerator) GetRandomId

func (gen *BufferedRandomIdGenerator) GetRandomId() string

GetRandomId returns a prefetched random id. Blocks till one is received.
