Struct Container 

pub struct Container<'a, 's, D, G> { /* private fields */ }

One original signature’s decoded Contents, including the padding required by VRI naming. This owner keeps the producing PDF Session and signature membership; it cannot be constructed from replacement caller CMS bytes.

Implementations

impl<'a, 's, D: Copy + Eq, G: Copy + Eq> Container<'a, 's, D, G>

pub fn signature(&self) -> Signature<'a, 's, D, G>

The exact original dictionary whose Contents this owner decoded.

pub fn contents(&self) -> &[u8]

Whole decoded Contents for VRI naming, including every padding octet.

pub fn der(&self) -> &[u8]

One exact DER ContentInfo extent, excluding checked zero padding.

pub fn read_timestamp<'q, W: Work + 'q>( &'q self, operation: &W, ) -> Result<(Token<'q>, Reader<'q>), ErrorOf<Infallible>>

Opens the original RFC3161 envelope without manufacturing another CMS input or dropping the PDF producing session’s depth/work boundary.

pub fn read<'q, W: Work + 'q>( &'q self, operation: &W, ) -> Result<(SignedData<'q>, Reader<'q>), ErrorOf<Infallible>>

Opens the same carried document under a current operation. Root ASN.1 depth is zero because a PDF string is not an ASN.1 enclosing element.

impl<D: Copy + Eq, G: Copy + Eq> Container<'_, '_, D, G>

pub fn vri_name<'p, P: AsnDigest<'p>, W: Work>( &self, provider: &'p P, operation: &W, ) -> Result<Option<Name>, NameError<P::Error>>

EN319142-1 §5.4.2.2(a) hashes all decoded Contents bytes, INCLUDING its unused padding, not just the parsed DER extent. SHA-1 here identifies a VRI dictionary; it does not grant a signature-algorithm permission. https://www.etsi.org/deliver/etsi_EN/319100_319199/31914201/01.02.01_60/en_31914201v010201p.pdf
