std::assert_eq!

macro_rules! assert_eq {
    ( $ left : expr , $ right : expr ) => { ... };
}

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

Examples

fn main() { let a = 3; let b = 1 + 2; assert_eq!(a, b); }

let a = 3;
let b = 1 + 2;
assert_eq!(a, b);
