Macro assertables::assert_set_superset

macro_rules! assert_set_superset {
    ($a_collection:expr, $b_collection:expr $(,)?) => { ... };
    ($a_collection:expr, $b_collection:expr, $($message:tt)+) => { ... };
}

Assert a set is a superset of another.

• If true, return ().

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

Examples

let a = [1, 2, 3];
let b = [1, 2];
assert_set_superset!(&a, &b);

let a = [1, 2];
let b = [1, 2, 3];
assert_set_superset!(&a, &b);
// assertion failed: `assert_set_superset!(a_collection, b_collection)`
//  a label: `&a`,
//  a debug: `[1, 2]`,
//  b label: `&b`,
//  b debug: `[1, 2, 3]`,
//        a: `{1, 2}`,
//        b: `{1, 2, 3}`

This implementation uses std::collections::BTreeSet to count items and sort them.
