Types

type ErrorType

type ErrorType string

ErrorType is not empty if result status is not success

type Result

type Result struct {
	// ErrorType is the type of result if Status is not success
	ErrorType ErrorType `json:"errorType,omitempty"`
	// Err indicate the error detail
	Err string `json:"error,omitempty"`
	// Data is the real data of result, data may be nil even if Status is success
	Data interface{} `json:"data,omitempty"`
	// Status indicate whether the result is success
	Status Status `json:"status"`
}

Result is the common format of all response
