Function one_sided_polyline_hausdorff_distance 

pub fn one_sided_polyline_hausdorff_distance(
    a: &[DVec3],
    b: &[DVec3],
) -> Result<f64, FrechetError>

The supremum, over every point of polyline a, of that point’s distance to the nearest point of polyline b. Both curves are treated as continuous piecewise-linear point sets, not just their vertices.

This is not symmetric: a can lie entirely close to b while b has stretches far from a (for example, a short segment sitting directly above the middle of a much longer one). Use polyline_hausdorff_distance for the symmetric, two-sided distance.

Errors

An empty polyline or a non-finite coordinate.
