Struct ExpressionGraph 

pub struct ExpressionGraph {
    pub roots: BTreeMap<SemanticId, SemanticId>,
    pub nodes: BTreeMap<SemanticId, ExpressionNode>,
}

Canonical compiler-owned graph for all lowered state initializer and computed expressions.

Fields

roots: BTreeMap<SemanticId, SemanticId>

nodes: BTreeMap<SemanticId, ExpressionNode>

Implementations

impl ExpressionGraph

pub fn from_components( components: &[ComponentNode], provenance: &BTreeMap<SemanticId, SourceProvenance>, ) -> Self

Panics

Panics when an expression owner has no canonical source provenance.

pub fn root_for(&self, owner: &SemanticId) -> Option<&SemanticId>

pub fn node(&self, id: &SemanticId) -> Option<&ExpressionNode>

pub fn nodes_for(&self, owner: &SemanticId) -> Vec<&ExpressionNode>

pub fn dependencies_of(&self, id: &SemanticId) -> Vec<&SemanticId>

pub fn dependents_of(&self, id: &SemanticId) -> Vec<&ExpressionNode>

pub fn owner_of(&self, id: &SemanticId) -> Option<&SemanticId>

pub fn provenance_of(&self, id: &SemanticId) -> Option<&SourceProvenance>

pub fn nodes_in_file(&self, path: &Path) -> Vec<&ExpressionNode>

pub fn nodes_at(&self, path: &Path, offset: usize) -> Vec<&ExpressionNode>

pub fn evaluate( &self, owner: &SemanticId, ) -> Option<Result<SerializableValue, ConstantEvaluationError>>

pub fn render(&self, owner: &SemanticId) -> Option<String>
