func Hmac(secretKey string, data string) (*string, error)

func IsAPIError

func IsAPIError(e error) bool

IsAPIError check if e is an API error

func Rsa

func Rsa(secretKey string, data string) (*string, error)

func SignFunc

func SignFunc(keyType string) (func(string, string) (*string, error), error)

Types

type APIError

type APIError struct {
	Code     int64  `json:"code"`
	Message  string `json:"msg"`
	Response []byte `json:"-"` // Assign the body value when the Code and Message fields are invalid.
}

APIError define API error when response status is 4xx or 5xx

func (APIError) Error

func (e APIError) Error() string

Error return error code and message

func (APIError) IsValid

func (e APIError) IsValid() bool

type PriceLevel

type PriceLevel struct {
	Price    string
	Quantity string
}

PriceLevel is a common structure for bids and asks in the order book.

func (*PriceLevel) Parse

func (p *PriceLevel) Parse() (float64, float64, error)

Parse parses this PriceLevel's Price and Quantity and returns them both. It also returns an error if either fails to parse.
