    pub creator: Option<String>,

}

PDF metadata extracted without loading the entire document. This is useful for quickly getting basic information about large PDFs.

Fields

title: Option<String>

Document title from Info dictionary

author: Option<String>

Document author from Info dictionary

subject: Option<String>

Document subject from Info dictionary

keywords: Option<String>

Document keywords from Info dictionary

creator: Option<String>

Application that created the document

producer: Option<String>

Application that produced the document

creation_date: Option<String>

Document creation date (PDF date format: D:YYYYMMDDHHmmSSOHH’mm’)

modification_date: Option<String>

Document modification date (PDF date format: D:YYYYMMDDHHmmSSOHH’mm’)

custom: HashMap<Vec<u8>, Object>

Custom Info dictionary entries that are not part of the standard set above.

Producers commonly use the Info dictionary to attach application-specific metadata (for example, Microsoft Information Protection labels stored as MSIP_Label_{GUID}_{Property} keys). Such entries used to be discarded by the metadata-only loader; they are now preserved here as raw Object values so callers can inspect or decode them as needed.

page_count: u32

Number of pages in the document

version: String

PDF version
