Macro core::assert_ne1.13.0 [] [src]

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

Asserts that two expressions are not equal to each other.

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

Like assert!(), this macro has a second version, 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");Run
