Function assert_persist_future_send 

fn assert_persist_future_send(
    store: &mut TursoStore,
    client: &mut Client<JournaledSession>,
)

Available on crate feature turso only.

Compile-time guard that TursoStore::persist returns a Send future.

The connection event loop drives persist from a tokio::spawned task, which requires Send futures. turso Statements are !Sync, so persist takes &mut self (a &mut TursoStore is Send as long as the store is); this pins that down. load runs before the task is spawned, so it is exempt. Never called; it only needs to type-check.
