Functions

func KrakenPriceFunction

func KrakenPriceFunction(
	response *http.Response,
	tickerToExponent map[string]int32,
	resolver types.Resolver,
) (tickerToPrice map[string]uint64, unavailableTickers map[string]error, err error)

KrakenPriceFunction transforms an API response from Kraken into a map of tickers to prices that have been shifted by a market-specific exponent.

Types

type KrakenResponseBody

type KrakenResponseBody struct {
	// As of this time, the Kraken API response is all-or-nothing - either valid ticker data, or one or more errors,
	// but not both. We enforce this expectation by defining mutual exclusivity in the validation tags of the Errors
	// field so that any validated API result always meets our expectation in the response parsing logic.
	Errors  []string                      `json:"error" validate:"omitempty"`
	Tickers map[string]KrakenTickerResult `validate:"required_without=Errors,excluded_with=Errors,dive" json:"result"`
}

type KrakenTickerResult

type KrakenTickerResult struct {
	AskPriceStats   []string `json:"a" validate:"len=3,dive,positive-float-string"`
	BidPriceStats   []string `json:"b" validate:"len=3,dive,positive-float-string"`
	ClosePriceStats []string `json:"c" validate:"len=2,dive,positive-float-string"`
	// contains filtered or unexported fields
}
