Struct PdfDocTimestamp 

pub struct PdfDocTimestamp {
    pub byte_range: [i64; 4],
    pub contents: Vec<u8>,
    pub sub_filter: Option<String>,
    pub filter: Option<String>,
}

One PDF /DocTimeStamp signature, surfaced separately from regular signatures so callers don’t have to filter the PdfSignature list.

A DocTimeStamp’s /Contents is an RFC 3161 TimeStampToken — a DER ContentInfo of type id-signedData whose eContentType is id-ct-TSTInfo (1.2.840.113549.1.9.16.1.4). The TST embeds the hash of the byte-ranged PDF content; callers who want to verify the stamp re-hash pdf[a..a+b] ‖ pdf[c..c+d] with the imprint’s algorithm and compare with the messageImprint.hashedMessage field of the inner TSTInfo.

Round 34 surfaces the timestamp structurally; full RFC 3161 verification dispatch (cert chain + GenTime ordering) lives in a follow-up round.

Fields

byte_range: [i64; 4]

/ByteRange [a b c d] — same shape as PdfSignature::byte_range.

contents: Vec<u8>

/Contents hex-decoded — the raw RFC 3161 TimeStampToken bytes.

sub_filter: Option<String>

/SubFilter — ETSI.RFC3161 for a conformant DocTimeStamp.

filter: Option<String>

/Filter — typically Adobe.PPKLite.
