Struct ElementFingerprint

pub struct ElementFingerprint {
    pub tag: String,
    pub classes: Vec<String>,
    pub attr_names: Vec<String>,
    pub depth: u32,
}

Expand description

A structural snapshot of a DOM element for similarity comparison.

Serialisable so callers can persist fingerprints across sessions.

§Example

use stygian_browser::similarity::ElementFingerprint;

let fp = ElementFingerprint {
    tag: "div".to_string(),
    classes: vec!["card".to_string(), "highlighted".to_string()],
    attr_names: vec!["data-id".to_string()],
    depth: 3,
};
let json = serde_json::to_string(&fp).unwrap();
let back: ElementFingerprint = serde_json::from_str(&json).unwrap();
assert_eq!(fp.tag, back.tag);

Fields§

§tag: String

Lower-case tag name (e.g. "div", "a").

§classes: Vec<String>

Sorted CSS class list (excluding the empty string).

§attr_names: Vec<String>

Sorted attribute names present on the element, excluding "class" and "id".

§depth: u32

Distance from <body> in the DOM tree (direct children of <body> have depth 0).
