Struct DocumentMetadata 

pub struct DocumentMetadata {
    pub title: Option<String>,
    pub author: Option<String>,
    pub subject: Option<String>,
    pub keywords: Option<String>,
    pub creator: Option<String>,
    pub producer: Option<String>,
    pub creation_date: Option<String>,
    pub mod_date: Option<String>,
}

Document-level metadata extracted from the PDF /Info dictionary.

All fields are optional since PDFs may omit the /Info dictionary entirely or include only a subset of fields.

PDF Date Format

Date fields (creation_date, mod_date) are stored as raw PDF date strings in the format D:YYYYMMDDHHmmSSOHH'mm'. Use [DocumentMetadata::parse_pdf_date] to extract components.

author: Option<String>

Document author.

subject: Option<String>

Document subject / description.

keywords: Option<String>

creation_date: Option<String>

mod_date: Option<String>

Date the document was last modified (raw PDF date string).

Implementations

impl DocumentMetadata

pub fn is_empty(&self) -> bool

Returns true if all metadata fields are None.

Trait Implementations

impl Clone for DocumentMetadata

fn clone(&self) -> DocumentMetadata

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DocumentMetadata

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for DocumentMetadata

fn default() -> DocumentMetadata

Returns the “default value” for a type.

impl PartialEq for DocumentMetadata

fn eq(&self, other: &DocumentMetadata) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
