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

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

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

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.


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