Expand description
Assert a set is a superset of another.
Pseudocode:
(collection1 into set) ⊃ (collection2 into set)
-
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)`
// https://docs.rs/assertables/8.7.0/assertables/macro.assert_set_superset.html
// 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.
