Macro assertables::assert_bag_ne

macro_rules! assert_bag_ne {
    ($a:expr, $b:expr $(,)?) => { ... };
    ($a:expr, $b:expr, $($message:tt)+) => { ... };
}

Assert a bag is not equal to another.

• If true, return ().

• Otherwise, call panic! with a message and the values of the expressions with their debug representations.

Examples

// Return Ok
let a = [1, 1];
let b = [1, 1, 1];
assert_bag_ne!(&a, &b);
//-> ()

// Panic with error message
let result = panic::catch_unwind(|| {
let a = [1, 1];
let b = [1, 1];
assert_bag_ne!(&a, &b);
//-> panic!
});
assert!(result.is_err());
let actual = result.unwrap_err().downcast::<String>().unwrap().to_string();
let expect = concat!(
    "assertion failed: `assert_bag_ne!(left_bag, right_bag)`\n",
    "  left_bag label: `&a`,\n",
    "  left_bag debug: `[1, 1]`,\n",
    " right_bag label: `&b`,\n",
    " right_bag debug: `[1, 1]`,\n",
    "            left: `{1: 2}`,\n",
    "           right: `{1: 2}`"
);
assert_eq!(actual, expect);

// Panic with custom message
let result = panic::catch_unwind(|| {
let a = [1, 1];
let b = [1, 1];
assert_bag_ne!(&a, &b, "message");
//-> panic!
});
assert!(result.is_err());
let actual = result.unwrap_err().downcast::<String>().unwrap().to_string();
let expect = "message";
assert_eq!(actual, expect);

This implementation uses [BTreeMap] to count items and sort them.
