Types

type BaseProvider

type BaseProvider struct {
}

BaseProvider implements base provider functionality

func (*BaseProvider) BuildEntity

func (b *BaseProvider) BuildEntity(endpoint string, providerCode string, baseCurrency string, quotedCurrency string, rate float64, rateTime time.Time, providerTime time.Time) *entity.CurrencyRate

BuildEntity builds entity with given rates

func (*BaseProvider) GetRateGenerationTime

func (b *BaseProvider) GetRateGenerationTime(timeStr string) time.Time

GetRateGenerationTime returns time, when provider generates history rates for today and we can fetch it.

func (*BaseProvider) IsRequestValid

func (b *BaseProvider) IsRequestValid(p RatesProvider, ratesRequest model.RatesRequest) (bool, error)

IsRequestValid validates API call to provider.

type RatesProvider

type RatesProvider interface {
	GetCode() string
	GetConfig() model.ProviderConfig
	GetHistoricalRates(ratesRequest model.RatesRequest) (model.RatesResponse, error)
	GetLatestRates(ratesRequest model.RatesRequest) (model.RatesResponse, error)
	PreloadRates(date time.Time, save bool) (map[string]float64, map[string]float64, time.Time, error)
	GetRateGenerationTime() time.Time
	GetSupportedCurrencies() []string
	IsRequestValid(ratesRequest model.RatesRequest) (bool, error)
	GetLocation() *time.Location
	BuildEntity(endpoint string, baseCurrency string, quotedCurrency string, rate float64, rateDate time.Time, providerDate time.Time) *entity.CurrencyRate
}

RatesProvider for all currency rates providers

type Registry

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

Registry is providers container

func BuildRegistry

func BuildRegistry() (*Registry, error)

BuildRegistry constructor

func (*Registry) AddProvider

func (r *Registry) AddProvider(provider RatesProvider)

AddProvider add provider instance to Registry

func (*Registry) GetProvider

func (r *Registry) GetProvider(code string) (RatesProvider, error)

GetProvider returns provider's instance from Registry by code
