Struct MetadataConfig 

pub struct MetadataConfig {
    pub extract_document: bool,
    pub extract_headers: bool,
    pub extract_links: bool,
    pub extract_images: bool,
    pub extract_structured_data: bool,
    pub max_structured_data_size: usize,
}

Configuration for metadata extraction granularity.

Controls which metadata types are extracted and size limits for safety.

Examples

let config = MetadataConfig {
    extract_document: true,
    extract_headers: true,
    extract_links: true,
    extract_images: true,
    extract_structured_data: true,
    max_structured_data_size: 1_000_000,
};

assert!(config.extract_headers);

Fields

extract_document: bool

Extract document-level metadata (title, description, author, etc.)

extract_headers: bool

Extract h1-h6 header elements and their hierarchy

extract_links: bool

Extract anchor (a) elements as links with type classification

extract_images: bool

Extract image elements and data URIs

extract_structured_data: bool

Extract structured data (JSON-LD, Microdata, RDFa)

max_structured_data_size: usize

Maximum total size of structured data to collect (bytes) Prevents memory exhaustion on malformed or adversarial documents
