Function scalarString

pkg/modelerrors/modelerrors.go:764–778

scalarString renders a JSON scalar as text. JSON numbers decode to float64; whole numbers are rendered without a trailing ".0" so a code of 400 prints as "400". Returns "" for nil and empty strings.

(v any)

// whole numbers are rendered without a trailing ".0" so a code of 400 prints
// as "400". Returns "" for nil and empty strings.
func scalarString(v any) string {
	switch x := v.(type) {
	case nil:
		return ""
	case string:
		return x
	case float64:
		if x == float64(int64(x)) {
			return strconv.FormatInt(int64(x), 10)
		}
		return strconv.FormatFloat(x, 'g', -1, 64)
	default:
		return fmt.Sprint(v)
	}
