Types

type Cube

type Cube struct {
	Currency string `xml:"currency,attr"`
	Rate     string `xml:"rate,attr"`
}

type Cubes

type Cubes struct {
	CubeData []Cube `xml:"Cube>Cube>Cube"`
}

type ExchangeRatesHandler

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

func GetExchangeRatesHandler

func GetExchangeRatesHandler(log *zap.Logger) (*ExchangeRatesHandler, error)

func (ExchangeRatesHandler) GetRates

func (e ExchangeRatesHandler) GetRates(base, dest string) (float64, error)

func (*ExchangeRatesHandler) MonitorRates

func (e *ExchangeRatesHandler) MonitorRates(interval time.Duration) chan struct{}

MonitorRates checks the rates in the ECB API every interval and sends a message to the returned channel when there are changes

Note: the ECB API only returns data once a day, this function only simulates the changes in rates for demonstration purposes
