/*! \file macros.hpp
    \brief Preprocessor macros that can customise the cereal library

    By default, cereal looks for serialization functions with very
    specific names, that is: serialize, load, save, load_minimal,
    or save_minimal.

    This file allows an advanced user to change these names to conform
    to some other style or preference.  This is implemented using
    preprocessor macros.

    As a result of this, in internal cereal code you will see macros
    used for these function names.  In user code, you should name
    the functions like you normally would and not use the macros
    to improve readability.

//! Whether cereal should be compiled for a threaded environment
/*! This macro causes cereal to use mutexes to control access to
    global internal state in a thread safe manner.

    Note that even with this enabled you must still ensure that
    archives are accessed by only one thread at a time; it is safe
    to use multiple archives in paralel, but not to access one archive
    from many places simultaneously. */

    std::size_t.

    More information can be found in cereal/details/helpers.hpp.

    size type (e.g. uint32_t). */
