Fields§

§unresolved_ctxt: SyntaxContext

This [SyntaxContext] should be applied only to unresolved references.

In other words, this should be applied to identifier references to global objects like Object or Math, and when those are not shadowed by a local declaration.

§is_unresolved_ref_safe: bool

True for argument of typeof.

Implementations§

source§

impl ExprCtx

source

pub fn preserve_effects<I>(&self, span: Span, val: Expr, exprs: I) -> Expr
where I: IntoIterator<Item = Box<Expr>>,

make a new expression which evaluates val preserving side effects, if any.

source

pub fn extract_side_effects_to(&self, to: &mut Vec<Box<Expr>>, expr: Expr)
