pub type RowPredicate = Rc<dyn Fn(&OwnedRow) -> bool>;Expand description
The in-memory predicate compiled from a connection’s pushed-down filter
(createPredicate, owned by 07). Rc so a fetch can clone it into the
returned lazy stream without holding a RefCell borrow on connection state
across the vend (the cardinal rule — foundations §6.2). The memory leaf reads
columns by ColId index; a bare &Row keeps this backend-agnostic.
