|
// 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 accessors.
|
//! @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 `BOOST_HANA_ADAPT_STRUCT`,
|
//! this macro requires specifying the way to retrieve each member by
|
//! providing a function that does the extraction.
|
//!
|
//! @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_adt.cpp
