Macro static_assertions_next::assert_align_lt

macro_rules! assert_align_lt {
    ($x:ty, $($y:ty),+ $(,)?) => { ... };
}

Asserts that the types’ alignments are less than each other.

Examples

A u8 has smaller alignment than u16, which has smaller alignment than a pointer:

assert_align_lt!(u8, u16, *const u8);

The following example fails to compile because a usize has the same alignment as a pointer:

assert_align_lt!(*const u8, usize);
