Struct Binding 

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

One exact signature VRI selected by the normative whole-Contents name. The actual parsed historical owner and root container cannot be replaced with caller-supplied signature octets or another VRI’s timestamp.

Implementations

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

pub fn vri(&self) -> &Vri

Actual matching original VRI, preserving its independent TU/TS method.

pub fn check_timestamp<'q, 'certificate, P, PE, RE>( &'q self, root: &'q SignedData<'_>, parent: &'q Reader<'q>, provider: &'q P, context: &'q CheckContext<'certificate, 'q>, recognizes: impl FnMut(&TokenExtension<'_>, &Execution<'_>) -> Result<bool, RE>, ) -> Result<Option<Time<'q, 'certificate, D, G>>, TimestampError<'q, PE, RE>>

where P: for<'scope> SignatureProvider<'scope, Error = PE>, 'v: 'q, 'certificate: 'q,

Checks the existing parsed TS over the root CMS encryptedDigest content octets, not the complete CMS value, PDF bytes or VRI name. EN319142-1 §5.4.2.3 note1 defines this exact input. A TU-only or subsequent-DTS method returns None without invoking crypto callbacks. https://www.etsi.org/deliver/etsi_en/319100_319199/31914201/01.02.01_60/en_31914201v010201p.pdf
