Struct Preparation 

pub struct Preparation<'p, 'm, 'd, 'a, 's, D, G> { /* private fields */ }

Immutable PAdES format preparation. The complete nested CMS participant and token census is borrowed from its owning common preparation unchanged. This is not a signature, authority, chronology or trust verdict.

Implementations

impl<'p, 'm, 'd, 'a, 's, D: Copy + Eq, G: Copy + Eq> Preparation<'p, 'm, 'd, 'a, 's, D, G>

pub async fn verify<'v, S, P>( &'v self, document: &'v Document<'s, S>, provider: &'v P, key: WorkingKey<'v>, parent: &Reader<'v>, ) -> Result<Mathematical<'v, 'p, 'm, 'd, 'a, 's, D, G>, CheckError<S::Error, P::Error>>

where S: RangeSource<Document = D, Generation = G>, P: SignatureProvider<'v>, 'm: 'v, 'd: 'v, 'a: 'v, 's: 'v,

Resolves and verifies the original detached root through the common asynchronous CMS driver. The source is constructed here from the exact prepared PDF signature, never accepted as a replacement caller payload.

impl<'p, 'm, 'd, 'a, 's, D: Copy + Eq, G: Copy + Eq> Preparation<'p, 'm, 'd, 'a, 's, D, G>

pub async fn read<S: RangeSource<Document = D, Generation = G>, W: Work>( document: &Document<'s, S>, container: &'p Container<'a, 's, D, G>, cms: &'p CmsPreparation<'m, 'd>, requested: Level, parent: &Reader<'d>, operation: &W, ) -> Result<Self, PrepareError<S::Error>>

Reads all root obligations before key resolution or payload acquisition. EN319142-1 §§4.1/6.3 Table1 overrides CAdES’s root signing-time field; the existing nested participant/token mechanisms are not reimplemented. https://www.etsi.org/deliver/etsi_EN/319100_319199/31914201/01.02.01_60/en_31914201v010201p.pdf

Panics

Panics if the inspected signature loses its original Contents member.

pub fn requested(&self) -> Level

Requested level, independent of optional timestamp presence.

pub fn claimed_time(&self) -> Option<Date>

Parsed claimed calendar label, without an occurrence proof.

pub fn placement(&self) -> Option<&Placement>

Actual historical signature-field and certification placement facts.

pub fn findings(&self) -> &[Finding]

Every retained root preparation finding, without successful-subset filtering.

pub fn all_basic_format_requirements_met(&self) -> bool

Only original baseline format facts, before mathematical verification.

pub fn cms(&self) -> &'p CmsPreparation<'m, 'd>

Existing whole CMS/counter/token preparation, not a copied catalogue.
