rust: static_assert: add `static_assert!` macro Add the `static_assert!` macro, which is a compile-time assert, similar to the C11 `_Static_assert` and C++11 `static_assert` declarations [1,2]. Do so in a new module, called `static_assert`. For instance: static_assert!(42 > 24); static_assert!(core::mem::size_of::<u8>() == 1); const X: &[u8] = b"bar"; static_assert!(X[1] == b'a'); const fn f(x: i32) -> i32 { x + 2 } static_assert!(f(40) == 42); Link: https://en.cppreference.com/w/c/language/_Static_assert [1] Link: https://en.cppreference.com/w/cpp/language/static_assert [2] Co-developed-by: Alex Gaynor <alex.gaynor@gmail.com> Signed-off-by: Alex Gaynor <alex.gaynor@gmail.com> Signed-off-by: Miguel Ojeda <ojeda@kernel.org> 2022-11-10 17:41:36 +01:00
