Struct MetadataConfigUpdate 

pub struct MetadataConfigUpdate {
    pub extract_document: Option<bool>,
    pub extract_headers: Option<bool>,
    pub extract_links: Option<bool>,
    pub extract_images: Option<bool>,
    pub extract_structured_data: Option<bool>,
    pub max_structured_data_size: Option<usize>,
}

Partial update for MetadataConfig.

This struct uses Option<T> to represent optional fields that can be selectively updated. Only specified fields (Some values) will override existing config; None values leave the corresponding fields unchanged when applied via MetadataConfig::apply_update.

Fields

• extract_document: Optional override for document-level metadata extraction
• extract_headers: Optional override for heading element extraction
• extract_links: Optional override for link element extraction
• extract_images: Optional override for image element extraction
• extract_structured_data: Optional override for structured data extraction
• max_structured_data_size: Optional override for structured data size limit

Examples

let update = MetadataConfigUpdate {
    extract_document: Some(false),
    extract_headers: Some(true),
    extract_links: None,  // No change
    extract_images: None,  // No change
    extract_structured_data: None,  // No change
    max_structured_data_size: None,  // No change
};

let mut config = MetadataConfig::default();
config.apply_update(update);
assert!(!config.extract_document);
assert!(config.extract_headers);

Fields

extract_document: Option<bool>

Optional override for extracting document-level metadata.

When Some(true), enables document metadata extraction; Some(false) disables it. None leaves the current setting unchanged.

extract_headers: Option<bool>

Optional override for extracting heading elements (h1-h6).

When Some(true), enables header extraction; Some(false) disables it. None leaves the current setting unchanged.

extract_links: Option<bool>

Optional override for extracting anchor (link) elements.

When Some(true), enables link extraction; Some(false) disables it. None leaves the current setting unchanged.

extract_images: Option<bool>

Optional override for extracting image elements.

When Some(true), enables image extraction; Some(false) disables it. None leaves the current setting unchanged.

extract_structured_data: Option<bool>

Optional override for extracting structured data (JSON-LD, Microdata, RDFa).

When Some(true), enables structured data extraction; Some(false) disables it. None leaves the current setting unchanged.

max_structured_data_size: Option<usize>

Optional override for maximum structured data collection size in bytes.

When Some(size), sets the new size limit. None leaves the current limit unchanged. Use this to adjust safety thresholds for different documents.
