//      Read entropy from the given file, by default `/dev/urandom`.
//      If a token is provided, it is assumed to be the path to a file
//      to read entropy from. This is the default behavior if nothing
//      else is specified. This implementation requires storing state

//
// _LIBCPP_USING_ARC4_RANDOM
//      Use arc4random(). This allows obtaining random data even when
//      using sandboxing mechanisms. On some platforms like Apple, this
//      is the recommended source of entropy for user-space programs.
//      When this option is used, the token passed to `std::random_device`'s
//      constructor *must* be "/dev/urandom" -- anything else is an error.
//
// _LIBCPP_USING_GETENTROPY
//      Use getentropy().
//      When this option is used, the token passed to `std::random_device`'s
//      constructor *must* be "/dev/urandom" -- anything else is an error.
//
// _LIBCPP_USING_FUCHSIA_CPRNG
//      Use Fuchsia's zx_cprng_draw() system call, which is specified to
//      deliver high-quality entropy and cannot fail.
//      When this option is used, the token passed to `std::random_device`'s
//      constructor *must* be "/dev/urandom" -- anything else is an error.
//
// _LIBCPP_USING_WIN32_RANDOM
//      Use rand_s(), for use on Windows.
//      When this option is used, the token passed to `std::random_device`'s
//      constructor *must* be "/dev/urandom" -- anything else is an error.
