Enum ProjectionKnob

}
Expand description

Every graph-projection knob, enumerated so the guest/native surface contract is checked at compile time: adding a knob forces a classification in ProjectionKnob::reach and a key in ProjectionKnob::config_key (both wildcard-free matches), mirroring the capability every_variant_classified_exactly_once exhaustiveness test. This is the anti-drift guard for the guest/native gap issue #151 exposed. See docs/proposals/graphcompute_projection_parity_2026-07-19.md §4.

Variants§

§

NodeLabels

Scope to these vertex labels (nodeLabels).

§

EdgeTypes

Scope to these edge types (edgeTypes / relationshipTypes).

§

WeightProperty

Bind an edge property as the traversal weight (weightProperty).

§

IncludeReverse

Also build inbound adjacency (includeReverse).

§

NodeProperties

Materialize per-vertex property tensors (nodeProperties).

§

EdgeProperties

Materialize per-edge property tensors (edgeProperties).

§

CypherNodeQuery

Cypher-mode node selection query (nodeQuery).

§

CypherEdgeQuery

Cypher-mode edge selection query (edgeQuery).

§

CypherWeightColumn

Cypher-mode weight column (weightColumn).

§

NamedGraph

Named pre-registered projection (name).

Implementations§

Source§

impl ProjectionKnob

Source

pub const ALL: &'static [ProjectionKnob]

Every knob, the single source of truth the exhaustiveness test iterates.

Source

pub fn config_key(self) -> &'static str

The graphRef config key for this knob. Wildcard-free: a new variant fails to compile here until it is given a key.

Source

pub fn reach(self) -> KnobReach

How a guest reaches this knob. Wildcard-free: a new variant fails to compile here until it is classified.
