StringRef is a reference to a string owned by something else.
So it behaves like simple string, but it does not own pointer. When it is default constructed, it has empty string. You can freely copy or move around this struct, but never free its pointer. str() function can be used to export the content as std::string. StringRef is adopted from https://github.com/nghttp2/nghttp2/blob/29cbf8b83ff78faf405d1086b16adc09a8772eca/src/template.h#L376
