FakeBkgTools::Database::StringRef Struct Reference

Note: the following structure is used (instead of a simple std::string) so that XML line numbers can be printed in the error message, which requires keeping track of the position of the string in the original file. More...

Detailed Description

Note: the following structure is used (instead of a simple std::string) so that XML line numbers can be printed in the error message, which requires keeping track of the position of the string in the original file.

Might be rewritten around a std::string_view one day
