a_static_assert_expr(expr, msg)
Helper for using _Static_assert in expressions
_Static_assert is not an expression according to the C standard, so embedding it in macros used for assignment is not directly possible. This trickery gets around that problem.
- Parameters:
expr – The assertion expression
msg – The message to display during compilation if the assertion failed
-
a_assert_or_expression(condition, msg, expression)
Execute an expression if assertion passes
Assertion helper to enable _Static_assert usage in macros that are used to assign in constexpr context.
- Parameters:
condition – A constexpr condition that evaluates to non-0 for “pass” and 0 for “fail”
msg – The error message to present if the condition fails
expression – The expression to execute if the condition passes
- Returns:
Whatever
