pub fn run_value(run: &EvalRun, field: &str) -> Option<f64>Expand description
The value a metric field takes on one run. failed/passed/total are
promoted so a metric can be written against any evalset without the host
having to add fields; error_rate is derived (undefined, not zero, when
no case ran); anything else is read from the summary the host did write.
The proposal-time baseline and every later measurement go through this one
reader, so a rule cannot be admitted on one reading of a run and judged
on another.
