Fields

state: &'a mut CompilerState

program: Symbol

changed: bool

Have we actually modified the program at all?

const_not_evaluated: Option<Span>

The RHS of a const declaration we were not able to evaluate.

array_index_not_evaluated: Option<Span>

An array index which was not able to be evaluated.

array_length_not_evaluated: Option<Span>

An array length which was not able to be evaluated.

repeat_count_not_evaluated: Option<Span>

A repeat expression count which was not able to be evaluated.

Implementations

impl ConstPropagationVisitor<'_>

pub fn in_scope<T>( &mut self, id: NodeID, func: impl FnOnce(&mut Self) -> T, ) -> T

Enter the symbol table’s scope id, execute func, and then return to the parent scope.

pub fn emit_err(&self, err: StaticAnalyzerError)

Emit a StaticAnalyzerError.
