}Expand description
Schema descriptor for a sequence. Pure data — the runtime state lives
in the backing table __turso_internal_seq_<name> and is read from
disk by Insn::SequenceComputeNext + surrounding cursor bytecode on
every nextval/setval call. See core/translate/sequence.rs and the
disk-only design notes above.
Clone is implemented so Arc::make_mut can in-place edit the name
field during ALTER TABLE … RENAME TO … on an AUTOINCREMENT table —
keeping the sequence’s identity in sync with the parent table’s new
name without forcing a schema reparse.
