Struct Encryptor 

pub struct Encryptor<'a> { /* private fields */ }

Enciphers the strings and stream payloads of one indirect object.

Per ISO 32000-1 §7.6.2 the key is derived per object from its number and generation; the generation is always 0 here because that is what the writer emits, which is also what the C++ passes.

Borrowed rather than owned so one handler and one vector source serve a whole save, with only the object number changing per object.

Implementations

impl<'a> Encryptor<'a>

pub const fn new( handler: &'a SecurityHandler, ivs: &'a IvSource, object_number: u32, ) -> Self

An encryptor for the object numbered num.

pub fn encrypts_metadata(&self) -> bool

Whether this document’s metadata stream is enciphered along with everything else (/EncryptMetadata, default true).

Read by the stream encoder, which owns the exemption; see its docs for why we consult the flag where the C++ writer does not.

pub fn encrypt(&self, class: CryptClass, data: &[u8]) -> Vec<u8>

Encipher one run of bytes as a string or a stream payload.

The class never changes the result — PDFium refuses a document whose /StmF and /StrF differ — but naming it keeps the call site honest about what it is writing.

Trait Implementations

impl<'a> Clone for Encryptor<'a>

fn clone(&self) -> Encryptor<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Copy for Encryptor<'a>

impl<'a> Debug for Encryptor<'a>

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

Formats the value using the given formatter.
