func NewRegulator(configuration *schema.RegulationConfiguration, provider storage.RegulatorProvider, clock utils.Clock) *Regulator

NewRegulator create a regulator instance.

func (*Regulator) Mark

func (r *Regulator) Mark(ctx context.Context, successful, banned bool, username, requestURI, requestMethod, authType string, remoteIP net.IP) error

Regulate the authentication attempts for a given user. This method returns ErrUserIsBanned if the user is banned along with the time until when the user is banned.
