pub fn lookup(id: &str) -> Option<&'static MetricInfo>Expand description
Catalog entry for a known offender id, or None. Callers pick their
own fallback for unknown ids (SARIF emits the raw id; Code Climate
falls through to its default message).
Public so out-of-crate consumers (the CLI threshold engine) can read
a metric’s Direction — the mi.* family is lower-is-worse, so
the gate and the offender wording must consult it rather than
assuming a higher value is always the violation (#698).
