pub fn measure(
s: &Setup<'_>,
author: impl FnOnce(&[(String, String)]) -> Authored,
) -> Result<AcceptanceStrength, String>Expand description
Measures the set. author is asked for variants (after the mutants, so a
slow tool leaves the call for last only when there is budget). Err: the
tree or the judge inputs did not come back as they were, and the
measurement is void.
