Andrey, a question: let's say I am the author of a uuid type, something like:
struct uuid { unsigned char value_[16]; };
How do I integrate that type in the proposed convert framework, so it can be converted to std::string? I have a basic understanding, but I wanted to see a clear picture of only the things relevant to defining a conversion (as opposed to using it.)
With the code snippet I attached it should look something like this: struct uuid_to_string_tag {}; template< typename ToT > typename enable_if< is_string< ToT >, uuid_to_string_tag
::type get_conversion_tag(uuid*, ToT*);
template< > struct converter_impl< uuid, uuid_to_string_tag > { typedef uuid result_type; template< typename ArgsT > result_type operator() (ArgsT const& args) const; }; The operator() will contain the conversion code.
