macro_rules! assert_eq_size_val { ($x:expr, $($xs:expr),+ $(,)?) => { ... }; }
Expand description
Asserts that values are equal in size.
This macro doesn’t consume its arguments and thus works for
non-Clone
able values.
§Examples
struct Byte(u8);
let x = 10u8;
let y = Byte(42); // Works for non-cloneable types
assert_eq_size_val!(x, y);
assert_eq_size_val!(x, y, 0u8);
Even though both values are 0, they are of types with different sizes:

assert_eq_size_val!(0u8, 0u32);
