pub fn wal_segment_id_start_seq(segment_id: &str) -> Option<ChangeSeq>Expand description
Start seq encoded in a WAL segment id’s 20-digit position prefix.
Returns None when the value does not follow the generated id shape, so
listings can skip foreign objects instead of failing. Like the name
itself, the parsed position is an inspection and reclamation hint only —
recovery authority is the head and chain.
