- // Note:
- // The weird definition as a variable seems to exploit a glitch in Doxygen
- // which makes the macro appear in the related objects of Struct (as we
- // want it to).
- //! Defines a model of `Struct` with the given members.
- //! @ingroup group-Struct
- //!
- //! Using this macro at _global scope_ will define a model of the `Struct`
- //! concept for the given type. This can be used to easily adapt existing
- //! user-defined types in a ad-hoc manner. Unlike the
- //! `BOOST_HANA_DEFINE_STRUCT` macro, this macro does not
- //! require the types of the members to be specified.
- //!
- //! @note
- //! This macro only works if the tag of the user-defined type `T` is `T`
- //! itself. This is the case unless you specifically asked for something
- //! different; see `tag_of`'s documentation.
- //!
- //!
- //! Example
- //! -------
- //! @include example/adapt_struct.cpp
- #ifdef BOOST_HANA_DOXYGEN_INVOKED
