Struct PriorSequence 

pub struct PriorSequence<'record, 'document> { /* private fields */ }

Immutable DER input covering EVERY chain preceding an actual new chain.

The surrounding sequence receives its required minimal DER length. Chain values are projected through the shared encoding kernel; BER wrappers and segmentation are not confused with DER bytes. No later chain or unprotected CryptoInfos/EncryptionInfo is included (§5.2 steps3–4).

Implementations

impl<'r, 'd> PriorSequence<'r, 'd>

pub fn new( record: &'r EvidenceRecord<'d>, before_chain: usize, operation: &Reader<'d>, ) -> Result<Self>

Binds the prefix to the actual new chain and admits it before hashing.

pub fn before_chain(&self) -> usize

The selected new chain ordinal; no order is inferred from timestamps.
