transactions abstract method
The transaction history for the activity list (FR-1), newest first and
paginated by an OPAQUE keyset cursor: pending (unmined) rows sort above
confirmed ones; after is null for the first page or the previous
HistoryPage.nextCursor for the following page (passed back VERBATIM — never
parse it); limit caps the page (clamped Rust-side). The keyset cursor means a
page boundary never drops a same-height row nor strands the confirmed history
behind a full page of pending txs. Each TxSummary carries the SIGNED net
amount, status/confirmations, fee, and a memo flag — DISPLAY data only (no key
material; §5.4 NEVER-LOG: txids/amounts/cursors). Reads librustzcash's
v_transactions view off the sync lock, so it's cheap and never blocks scanning.
Implementation
Future<HistoryPage> transactions({required int limit, String? after});
