Implementations§

impl ExprDagBuilder

Signature links:§ExprDagBuilder

pub fn new() -> ExprDagBuilder

Signature links:newExprDagBuilder

Empty expression arena.

pub fn push(&mut self, node: ExprNode) -> Result<ExprId, Diagnostic>

Signature links:pushExprNodeResultExprIdDiagnostic

Append one node and return its stable local ID.

pub fn constant(&mut self, value: DynQuantity) -> Result<ExprId, Diagnostic>

Signature links:constantDynQuantityResultExprIdDiagnostic

Add a dimensioned constant.

pub fn symbol(&mut self, symbol: SymbolRef) -> Result<ExprId, Diagnostic>

Signature links:negExprIdResultExprIdDiagnostic

Add unary negation.

pub fn add(&mut self, left: ExprId, right: ExprId) -> Result<ExprId, Diagnostic>

Signature links:addExprIdExprIdResultExprIdDiagnostic

Add two expressions.

pub fn sub(&mut self, left: ExprId, right: ExprId) -> Result<ExprId, Diagnostic>

Signature links:subExprIdExprIdResultExprIdDiagnostic

Subtract two expressions.

pub fn mul(&mut self, left: ExprId, right: ExprId) -> Result<ExprId, Diagnostic>

Raise an expression to an integer power.

pub fn spatial_coordinate(&mut self, axis: usize) -> Result<ExprId, Diagnostic>

Signature links:spatial_coordinateusizeResultExprIdDiagnostic

Read one physical Cartesian coordinate from the owning Relation’s Domain.

pub fn unary_math( &mut self, function: UnaryMathFunction, value: ExprId, ) -> Result<ExprId, Diagnostic>

Signature links:unary_mathUnaryMathFunctionExprIdResultExprIdDiagnostic

Apply a dimension-aware unary mathematical function.

pub fn gradient(&mut self, value: ExprId) -> Result<ExprId, Diagnostic>

Signature links:gradientExprIdResultExprIdDiagnostic

Take the physical-space gradient.

pub fn divergence(&mut self, value: ExprId) -> Result<ExprId, Diagnostic>

Signature links:divergenceExprIdResultExprIdDiagnostic

pub fn pure_operator( &mut self, definition: &PureOperatorDefinition, arguments: impl IntoIterator<Item = ExprId>, ) -> Result<ExprId, Diagnostic>

Signature links:pure_operatorPureOperatorDefinitionIntoIteratorExprIdResultExprIdDiagnostic

Apply one closed pure-operator definition to prior expressions.

The definition is deduplicated by its exact content digest and retained inside the finished expression. Arguments remain ordered by formal slot; there is no name lookup or implicit commutativity.

§Errors

Returns EQ0301 for an empty or inexact argument list, a forward reference, or the cryptographically exceptional case in which equal digests identify unequal canonical definitions.

pub fn finish( self, roots: impl IntoIterator<Item = ExprId>, ) -> Result<ExprDag, Diagnostic>

Signature links:finishIntoIteratorExprIdResultExprDagDiagnostic

Finish a DAG with one or more residual roots.

§Errors

Returns EQ0301 when the arena or root set is empty, or a root is not present in this arena.
