ShapeRelation

Struct ShapeRelation

pub struct ShapeRelation {
    pub left: ShapeNormalForm,
    pub right: ShapeNormalForm,
    pub kind: ShapeRelationKind,
    pub proven: bool,
    pub witnesses: Vec<ShapeWitness>,
    pub diagnostics: Vec<Diagnostic>,
}

Expand description

Conservative relation report between two shapes.

A relation is proven only when the runtime can establish it through subshape checks or explicit conservative rules. Probe-only overlap remains useful evidence but is not a proof.

Fields§

§left: ShapeNormalForm

Normal form for the left input shape.

§right: ShapeNormalForm

Normal form for the right input shape.

§kind: ShapeRelationKind

Best relation kind the runtime could determine.

§proven: bool

Whether the relation kind is proven rather than probe-derived.

§witnesses: Vec<ShapeWitness>

Probe results collected while comparing the shapes.

§diagnostics: Vec<Diagnostic>

Diagnostic notes explaining conservative proof rules.
