Types

type Counter

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

func (*Counter) Dec

func (r *Counter) Dec(release func())

Dec decrements the counter and calls the release function, if this is the last reference.

func (*Counter) Inc

func (r *Counter) Inc(init func() error) (err error)

Inc increments the counter and calls the init function, if this is the first reference. The call returns an error only if init call has failed, and the reference has not been incremented.
