fn filter<'a>(
entries: &'a [MatrixEntry],
label: Option<&str>,
) -> Result<Vec<&'a MatrixEntry>>Expand description
Returns the matrix entries to run, optionally filtered by label.
When label is None all entries are returned. When a label is
provided it is normalised via matrix::normalize_features_arg before
matching, so both "otel,test" and "otel + test" resolve to the same
entry. An unknown label after normalisation is an error.
ยงErrors
Returns an error when a label is provided but no matrix entry matches, listing all available labels.
