Description

Implementations§

§

impl ExprDag

Signature links:§ExprDag

pub fn nodes(&self) -> &[ExprNode]

Signature links:nodesExprNode

pub const fn definitions( &self, ) -> &BTreeMap<OperatorDefinitionDigest, PureOperatorDefinition>

Signature links:definitionsBTreeMapOperatorDefinitionDigestPureOperatorDefinition

Exact definitions in canonical digest order.

pub fn definition( &self, digest: OperatorDefinitionDigest, ) -> Option<&PureOperatorDefinition>

Signature links:definitionOperatorDefinitionDigestOptionPureOperatorDefinition

Resolve one application digest against this expression’s closed table.

pub fn node(&self, id: ExprId) -> Option<&ExprNode>

Signature links:nodeExprIdOptionExprNode

Look up a node by its arena ID.
