Struct ZoneMaps 

pub struct ZoneMaps {
    pub max_heading_depth: u8,
    pub heading_slugs: HashSet<String>,
    pub heading_contents: HashSet<String>,
    pub code_languages: HashSet<String>,
    pub frontmatter_keys: HashSet<String>,
    pub title: Option<String>,
    pub tags: Vec<String>,
}

Statistical metadata per document used for query pruning (Zone Maps).

Before scanning a document’s blocks, the query engine checks these statistics to decide whether the document can be skipped entirely.

Fields

max_heading_depth: u8

Maximum heading depth (1–6) found in the document.

heading_slugs: HashSet<String>

Set of heading slugs (lowercased, hyphenated) present in the document. Used to skip documents that don’t contain a requested heading.

heading_contents: HashSet<String>

Set of heading content strings (plain text) for exact-match skipping.

code_languages: HashSet<String>

Set of code-block language tags present (e.g. "rust", "python").

frontmatter_keys: HashSet<String>

Set of top-level front-matter keys.

title: Option<String>

Document title – from front-matter title field or first H1.

tags: Vec<String>

Tags list from front-matter tags array.
