Struct TrailerInfo 

pub struct TrailerInfo {
    pub root: ObjectId,
    pub info: Option<ObjectId>,
    pub encrypt: Option<ObjectId>,
    pub id: Option<[Vec<u8>; 2]>,
    pub size: u32,
    pub prev: Option<u64>,
}

Extracted information from the trailer dictionary.

Fields

root: ObjectId

The indirect reference to the document catalog (/Root).

info: Option<ObjectId>

Optional indirect reference to the document information dictionary (/Info).

encrypt: Option<ObjectId>

Optional indirect reference to the encryption dictionary (/Encrypt).

id: Option<[Vec<u8>; 2]>

Optional file identifier array (/ID).

size: u32

Total number of cross-reference entries (/Size).

prev: Option<u64>

Optional offset to the previous cross-reference section (/Prev).

Implementations

impl TrailerInfo

pub fn root_obj_num(&self) -> u32

Returns the object number of the document catalog (/Root).

Corresponds to CPDF_Parser::GetRootObjNum() in PDFium.

pub fn get_root_obj_num(&self) -> u32

ADR-019 alias for root_obj_num().

Corresponds to CPDF_Parser::GetRootObjNum() in PDFium.

pub fn info_obj_num(&self) -> Option<u32>

Returns the object number of the document information dictionary (/Info), or None if not present.

Corresponds to CPDF_Parser::GetInfoObjNum() in PDFium.

pub fn get_info_obj_num(&self) -> Option<u32>

ADR-019 alias for info_obj_num().

Corresponds to CPDF_Parser::GetInfoObjNum() in PDFium.

pub fn encrypt_dict(&self) -> Option<ObjectId>

Returns the object ID reference to the encryption dictionary (/Encrypt), or None if the document is not encrypted.

Corresponds to CPDF_Parser::GetEncryptDict() in PDFium (returns the reference rather than resolving the dictionary itself).

pub fn get_encrypt_dict(&self) -> Option<ObjectId>

ADR-019 alias for encrypt_dict().

Corresponds to CPDF_Parser::GetEncryptDict() in PDFium.

pub fn get_encrypt_id(&self) -> Option<ObjectId>

👎Deprecated:

use get_encrypt_dict() — matches upstream CPDF_Parser::GetEncryptDict()

Deprecated non-upstream alias for encrypt_dict().

There is no CPDF_Trailer::GetEncryptId() in PDFium upstream; the correct upstream method is CPDF_Parser::GetEncryptDict(), already covered by get_encrypt_dict(). Use get_encrypt_dict() instead.

pub fn encrypt_id(&self) -> Option<ObjectId>

👎Deprecated since 0.0.0:

use encrypt_dict() or get_encrypt_dict()

Rust-idiomatic alias for encrypt_dict().

pub fn id_array(&self) -> Option<&[Vec<u8>; 2]>

Returns a reference to the file identifier byte-string pair (/ID), or None if not present.

Corresponds to CPDF_Parser::GetIDArray() in PDFium.

pub fn get_id_array(&self) -> Option<&[Vec<u8>; 2]>

ADR-019 alias for id_array().

Corresponds to CPDF_Parser::GetIDArray() in PDFium.
