Function stringify

middleware/stack_values.go:92–100

stringify tries a bit to stringify v, without using fmt, since we don't want context depending on the unicode tables. This is only used by *valueCtx.String().

(v interface{})

// want context depending on the unicode tables. This is only used by
// *valueCtx.String().
func stringify(v interface{}) string {
	switch s := v.(type) {
	case stringer:
		return s.String()
	case string:
		return s
	}
	return "<not Stringer>"
}
