ComponentScalarization

eqiora::ir

Struct ComponentScalarization 

pub struct ComponentScalarization { /* private fields */ }
Description

Operator-lowering proof that shaped residuals mean componentwise zero.

Semantic expression nodes remain shaped. This lowered form alone expands roots into deterministic scalar rows; it does not add component-selection nodes to canonical meaning.

Implementations§

§

impl ComponentScalarization

Signature links:§ComponentScalarization

pub fn lower<I>( residual: &TypedResidual<I>, ) -> Result<ComponentScalarization, Diagnostic>
where I: Clone + Eq,

Signature links:lowerTypedResidualResultComponentScalarizationDiagnosticCloneEq

Scalarize one fully typed pointwise residual.

Rows are ordered by Relation root, then row-major component index. A scalar root contributes one row with an empty index. Spatial operators fail closed because their scalarization belongs to a discretized Operator lowering, not this pointwise contract.

§Errors

Returns EQ0701 for shape cardinality mismatch, unrepresentable row count, inconsistent repeated-symbol shape, a non-pointwise expression, or an invalid exact component coordinate.

pub fn rows(&self) -> &[ComponentScalarRow]

Signature links:rowsComponentScalarRow

Deterministic scalar residual rows.

pub fn evaluate( &self, resolve: impl FnMut(&ScalarSymbolCoordinate) -> Option<f64>, ) -> Result<Vec<f64>, Diagnostic>

Signature links:evaluateFnMutScalarSymbolCoordinateOptionf64ResultVecf64Diagnostic

Evaluate every row through one shaped-coordinate resolver.

§Errors

Returns EQ0702 when a coordinate is missing, or the underlying scalar Operator IR diagnostic for non-finite arithmetic.
