How to conditionally skip tests based on runtime information?

Question

Is it possible to programmatically skip some tests based on runtime information? For example, I would like cargo test to emit something like

test my_test ... skipped

instead of

test my_test ... ok

when cond() is evaluated to false in the following test:

#[test]
fn my_test() {
    if !cond() {
        // Mark the test as skipped. How?
        return;
    }

    // The actual test that works only when cond() returns true.
}

In other words, I am looking for a Rust alternative of unittest.skipTest() in Python (more information).

There is nothing built in for this; tests only succeed or fail.

The built in test runner is very minimal.
