Function soft 

pub fn soft<F>(f: F) -> Result<(), TestError>
where
    F: FnOnce(&mut SoftAsserter),

Runs f in a soft-assertion scope.

Inside f, failures recorded on the SoftAsserter do not end the closure. When f returns, soft returns Ok(()) if nothing was recorded, or a single TestError collecting every recorded failure.

If f panics, the panic does not swallow what was already recorded: soft runs f under catch_unwind, prints the collected soft failures to standard error, and then re-raises the panic so the test still fails on it.

    soft(|s| {
        s.check(&2, eq(2));
        s.check(&"alice", eq("alice"));
    })?;
    Ok(())
}
