Note
During standard data types conversion CppBind copies original data to the target language.
Note
In case of std::optional we are using type specific structures in Swift
to send the data to the target language. See CppBindOptional* structures in src/cppbind/config/std_helpers/swift/cxx/c_helpers.h
Examples
You can find standard data types examples on examples/primitives/cxx/stl_types and examples/primitives/cxx/containers directories.
