Macro const_assert_ne

macro_rules! const_assert_ne {
    ($x:expr, $y:expr $(,)?) => { ... };
}

Asserts that constants are not equal in value.

Examples

This works as a shorthand for const_assert!(a != b):

const NUM: usize = 32;

const_assert_ne!(NUM * NUM, 64);

The following example fails to compile because 2 is magic and 2 × 2 = 2 + 2:

const_assert_ne!(2 + 2, 2 * 2);
