Struct swc_plugin::utils::ExprCtx
[−]pub struct ExprCtx {
pub unresolved_ctxt: SyntaxContext,
pub is_unresolved_ref_safe: bool,
}
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
impl ExprCtx
impl ExprCtx
pub fn preserve_effects<I>(&self, span: Span, val: Expr, exprs: I) -> Expr where
I: IntoIterator<Item = Box<Expr, Global>>,
pub fn preserve_effects<I>(&self, span: Span, val: Expr, exprs: I) -> Expr where
I: IntoIterator<Item = Box<Expr, Global>>,
make a new expression which evaluates val
preserving side effects, if
any.
