BOOST_HANA_NAMESPACE_BEGIN
// 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

#define BOOST_HANA_ADAPT_STRUCT(Name, ...) see documentation
