Function jaccard_weighted 

pub fn jaccard_weighted(
    reference: &ElementFingerprint,
    candidate: &ElementFingerprint,
) -> f32

Compute the weighted Jaccard similarity between two element fingerprints.

Weights:

Component	Weight
Tag name match	0.40
Class list Jaccard	0.35
Attribute name Jaccard	0.15
Depth proximity	0.10

Returns a score in [0.0, 1.0].

Example

use stygian_browser::similarity::{ElementFingerprint, jaccard_weighted};

let a = ElementFingerprint { tag: "div".into(), classes: vec!["foo".into()], attr_names: vec![], depth: 2 };
let b = a.clone();
assert!((jaccard_weighted(&a, &b) - 1.0).abs() < 1e-6);
