Runtime preflight summary for an epistemic executable plan.

Fields

epistemic_mode: EirEpistemicMode

Selected epistemic semantics mode for the accepted GPU execution.

workspace_layout: EpistemicGpuWorkspaceLayout

GPU workspace layout required by the executable plan.

reduced_runtime_rule_count: usize

Compiled reduced-runtime rule count.

reduced_constraint_relation_count: usize

Compiler-generated reduced integrity-constraint relations to validate.

wcoj_required_reduction_count: usize

Reduced rules that the epistemic planner marked as requiring WCOJ eligibility.

multiway_reduction_count: usize

Number of reduced rules carrying a MultiWayJoin route.

kclique_wcoj_plan_count: usize

Number of K-clique WCOJ plans reused from the production planner.

wcoj_triangle_route_count: usize

Number of triangle WCOJ routes reused from the production runtime.

wcoj_4cycle_route_count: usize

Number of 4-cycle WCOJ routes reused from the production runtime.

free_join_route_count: usize

Generic Free Join multiway routes: plan: None nodes matching no dedicated kernel shape. Opportunistic by contract — the dispatcher may structurally decline to the embedded binary fallback (non-prefix bound columns, non-u32 inputs, …), so these routes carry no hard dispatch obligation and are excluded from the dedicated-WCOJ certification arithmetic.

kclique_wcoj_plan_count_by_arity: [usize; 4]

K-clique WCOJ plan counts by arity K=5..8.

kclique_wcoj_max_arity: u8

Maximum K-clique arity observed across production WCOJ plans.

kclique_wcoj_edge_permutation_count: usize

Live edge-permutation slots carried by production K-clique plans.

kclique_stream_group_count: usize

Distinct K-clique stream groups carried by production WCOJ plans.

kclique_skew_scheduled_plan_count: usize

K-clique WCOJ plans carrying helper-split skew scheduling metadata.

planned_hash_route_count: usize

Number of structured planned-hash routes.

planned_hash_planner_wins_count: usize

Planned-hash routes where complete planner costs predicted hash wins.

planned_hash_incomplete_stats_count: usize

Planned-hash routes selected because complete WCOJ stats were unavailable.

planned_hash_cost_evidence_count: usize

Planned-hash routes carrying finite hash-vs-WCOJ cost evidence.

sorted_layout_requirement_count: usize

Sorted-layout edge-slot requirements carried by WCOJ plans.

helper_split_spec_count: usize

Helper-splitting specs carried by WCOJ plans.

helper_relation_rule_count: usize

Compiler-created helper-split relation rules in the reduced runtime plan.

helper_relation_scan_count: usize

WCOJ input scans of compiler-created helper-split relations.

tuple_membership_binding_count: usize

Tuple-membership bindings certified for stable-model membership checks.

solver_assumption_binding_count: usize

Solver assumption bindings exported by the semantic plan.

solver_required_capability_count: usize

Solver production capabilities required by the semantic plan.

solver_required_status_count: usize

Distinct solver statuses required by the semantic plan.

know_operator_count: usize

Non-negated know operators represented by the executable GPU plan.

possible_operator_count: usize

Non-negated possible operators represented by the executable GPU plan.

not_know_operator_count: usize

Negated know operators represented as not know.

not_possible_operator_count: usize

Negated possible operators represented as not possible.

cpu_fallbacks: EpistemicCpuFallbackCounters

Forbidden CPU fallback counters copied from the GPU semantic contract.

Implementations

impl EpistemicGpuRuntimePreflight

pub fn is_g91_mode(&self) -> bool

Whether this accepted execution used Gelfond-1991 (G91) compatibility semantics.

pub fn is_faeel_mode(&self) -> bool

Whether this accepted execution used default FAEEL semantics.

pub fn for_executable_plan( executable: &EpistemicExecutablePlan, capacities: EpistemicGpuWorkspaceCapacities, ) -> Result<Self>

Inspect an executable epistemic plan before GPU kernel dispatch.

Trait Implementations

impl Clone for EpistemicGpuRuntimePreflight

fn clone(&self) -> EpistemicGpuRuntimePreflight

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EpistemicGpuRuntimePreflight

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

Formats the value using the given formatter.

impl PartialEq for EpistemicGpuRuntimePreflight

fn eq(&self, other: &EpistemicGpuRuntimePreflight) -> 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.
