pub struct BuilderCheckpoint { /* private fields */ }Expand description
An opaque snapshot of a MessageBuilder’s full encode state — write
cursor, header counts, and compression-table size. Used to speculatively
append an OPTIONAL record group (e.g. an RFC 6762 §6.1 NSEC) and roll back
cleanly if it does not fit, without discarding records already written.
