pub fn satisfies(declared: &str, installed: &str, pin: Pin) -> Option<bool>Expand description
Whether an installed version satisfies a declared one, or None when that cannot be
decided. Only plain dotted numbers are compared: a range (>=22), a channel name
(stable) or an answer that is not a version stays undecided, because a finding that
guesses fires on machines that are fine, and is then ignored when it is right.
