Macro expanding to the full version of the library, in hexadecimal //! representation. //! //! Specifically, `BOOST_HANA_VERSION` expands to an hexadecimal number of the //! form 0xVVRRPPPP, where `VV` is the major version of the library, `RR` is //! the minor version and `PPPP` is the patch level. This allows the version //! of the library to be compared: //! @snippet example/version.cpp main //! //! //! @note //! The major, minor and patch versions of the library are also available //! individually with the `BOOST_HANA_{MAJOR,MINOR,PATCH}_VERSION` macros. #define BOOST_HANA_VERSION \ BOOST_HANA_CONFIG_VERSION(BOOST_HANA_MAJOR_VERSION, \ BOOST_HANA_MINOR_VERSION, \ BOOST_HANA_PATCH_VERSION) \ /**/ #endif // !BOOST_HANA_VERSION_HPP
