User-Defined Formats The str_format library provides customization utilities for formatting user-defined types using StrFormat().As with most type extensions, you should own the type you wish to extend. To extend formatting to your custom type, provide an AbslFormatConvert() overload as a free (non-meer) function within the same file and namespace of that type, usually as a friend definition.
