Types ¶

type Counter ¶

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

Counter persists every admitted operation before returning success. A corrupt or unwritable counter fails closed instead of granting a fresh process-local allowance.

func Open ¶

func Open(dir, name string, limit int, window time.Duration) (*Counter, error)

Open loads a durable counter from an owner-only state directory.

func (*Counter) Close ¶

func (c *Counter) Close() error

Close releases the held state-directory descriptor.

func (*Counter) Take ¶

func (c *Counter) Take(now time.Time) (bool, error)

Take durably charges one operation. Clock rollback preserves the existing window until wall time catches up, preventing restart or time manipulation from replenishing the allowance.
