Macro assert_ne

macro_rules! assert_ne {
    ($left:expr, $right:expr $(,)?) => { ... };
    ($left:expr, $right:expr, $($arg:tt)+) => { ... };
}

Asserts that two expressions are not equal to each other (using PartialEq).

Assertions are always checked in both debug and release builds, and cannot be disabled. See debug_assert_ne! for assertions that are disabled in release builds by default.

On panic, this macro will print the values of the expressions with their debug representations.

Like assert!, this macro has a second form, where a custom panic message can be provided.

Examples

let a = 3;
let b = 2;
assert_ne!(a, b);

assert_ne!(a, b, "we are testing that the values are not equal");
