Struct ElementFingerprint 

pub struct ElementFingerprint {
    pub tag: String,
    pub attributes: BTreeMap<String, String>,
    pub text: Option<String>,
    pub path: Vec<String>,
    pub parent_name: Option<String>,
    pub parent_attribs: Option<BTreeMap<String, String>>,
    pub parent_text: Option<String>,
    pub siblings: Option<Vec<String>>,
    pub children: Option<Vec<String>>,
}

A serialized element fingerprint — everything the similarity scorer needs. Store it anywhere (file, DB, JSON column); it is plain data.

Fields

tag: String

attributes: BTreeMap<String, String>

Attribute name → value, whitespace-stripped, empties dropped (BTreeMap so serialization is deterministic).

text: Option<String>

The element’s own leading text (element.text in lxml terms), stripped.

path: Vec<String>

Root-to-element tag path.

parent_name: Option<String>

parent_attribs: Option<BTreeMap<String, String>>

parent_text: Option<String>

siblings: Option<Vec<String>>

children: Option<Vec<String>>
