assert_err!()

let result = "z".parse::<u32>();
assert_err!(result);

assert_some!()

let option = "5".parse::<u32>().ok();
assert_some!(option);

assert_some!().with_value()

let option = "5".parse::<u32>().ok();
assert_some!(option).with_value(5);

assert_none!()

Collections

assert_contains!()

let vec = vec![1, 3, 5, 7, 9, 11, 13, 15, 17, 19];
let x = 5;
assert_contains!(&vec, &x);

let mut map = HashMap::new();
map.insert("a", 1);
map.insert("b", 3);
let pair = (&"a", &1);
assert_contains!(&map, pair)

assert_all!()

let vec = vec![1, 3, 5, 7, 9, 11, 13, 15, 17, 19];
assert_all!(&vec, |&x| x > 0, "all > 0");

assert_any!()

let vec = vec![1, 3, 5, 7, 9, 11, 13, 15, 17, 19];
assert_any!(&vec, |&x| x > 0, "any > 0");

Inequalities

assert_lt!(x, y) // less than
assert_le!(x, y) // less or equal

assert_gt!(x, y) // greater than
assert_ge!(x, y) // greater or equal
