pub fn holes_of(
reader: &Reader<'_>,
features: &[FeatureRef],
) -> GeopResult<Vec<(String, HoleSite)>>Expand description
The holes of the features features — of the part reader reads, or
of parts placed in it — each by its name, behind its instance’s path,
and where the part read has it. A feature that drilled no hole is
refused by name.
