Struct JoinPrecheckReport 

pub struct JoinPrecheckReport {
    pub bounds: JoinPrecheckBounds,
    pub tracked_keys: usize,
    pub queries: Vec<(QueryId, Vec<JoinPrecheckState>)>,
}

Per-registered-query bookkeeping in the shared graph: the [PipelineManifest] (the exact node/storage slots its build created, for teardown) and the caller’s opaque QueryId tag. Keyed by the query’s change-sink NodeId. The engine does nothing with the tag (no de-dup / no refcount — that is the caller’s concern); it is retained for correlation/observability and echoed back via the Query handle. What Engine::join_precheck_report returns: the join membership pre-check’s bounds and per-query join states on one engine (design 311 §8 inspection).

Fields

bounds: JoinPrecheckBounds

The bounds in force on the engine’s graph.

tracked_keys: usize

Distinct parent keys charged against the per-graph budget right now.

queries: Vec<(QueryId, Vec<JoinPrecheckState>)>

Per registered query (sorted by id): the state of each join its pipeline owns, in build order.

Trait Implementations

impl Clone for JoinPrecheckReport

fn clone(&self) -> JoinPrecheckReport

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for JoinPrecheckReport

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

Formats the value using the given formatter.

impl PartialEq for JoinPrecheckReport

fn eq(&self, other: &JoinPrecheckReport) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
