Struct QueryIterBase 

pub struct QueryIterBase { /* private fields */ }

Base query iterator wrapping a binding source

Implementations

impl QueryIterBase

pub fn new(bindings: Vec<Binding>) -> Self

Create from binding list

pub fn empty() -> Self

Create empty iterator

pub fn single(binding: Binding) -> Self

Create single-result iterator

pub fn with_cancel(self, token: CancelToken) -> Self

Issue #808 / 750d — attach a shared cancel token. The scan checks it on every next_binding, so cancelling the token (from the stream layer on disconnect or explicit cancel) halts production within one row regardless of how many bindings remain.

Trait Implementations

impl BindingIterator for QueryIterBase

fn next_binding(&mut self) -> IterResult

Get next binding

fn has_next(&self) -> bool

Check if there are more results (optional hint)

fn vars(&self) -> Vec<Var>

Get variables produced by this iterator

fn cancel(&mut self)

Cancel iteration

fn reset(&mut self) -> bool

Reset iterator to beginning (if supported)

impl Debug for QueryIterBase

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
