HEXED_ASSERT

#define HEXED_ASSERT	(		expression,
			message,
			... )

Value:

  { \
  if (!(expression)) { \
    HEXED_THROW(format_str(1000, \
      "%s\n" \
      "  Assertion `%s` failed in `%s`.\n", \
      std::string(message).c_str(), #expression, __FUNCTION__) \
      __VA_OPT__(,) __VA_ARGS__ \
    ); \
  } \
}

Assert something with an informative error message.

If expression is false, throws an exception with HEXED_THROW. message and an optional third argument are passed to HEXED_THROW.

HEXED_THROW

#define HEXED_THROW	(		message,
			... )

Value:

  { \
  assert::throw_critical<__VA_ARGS__>(format_str(1000, \
    "%s\n" \
    "  At: line %d of `%s`\n" \
    "  In: %s", \
    std::string(message).c_str(), __LINE__, __FILE__, __PRETTY_FUNCTION__).c_str()); \
}

Throws an exception with an informative error message.

Throws an exception with a message that includes message plus some additional info for debugging. Works inside single-threaded regions as well as OpenMP parallel regions. If desired, supply the type of exception as the third argument. Exception type must be constructible from a string. Defaults to std::runtime_error.
