Trait Implementations

impl Default for UnbindVarVisitor

fn default() -> UnbindVarVisitor

Returns the “default value” for a type.

impl VisitAstMut for UnbindVarVisitor

fn visit<'a, T: AstVisitable>( &'a mut self, x: &mut T, ) -> ControlFlow<Self::Break>

Visit a visitable type. This calls the appropriate method of this trait on x (visit_$ty if it exists, visit_inner if not).

fn exit_de_bruijn_var<T: AstVisitable + Idx>( &mut self, var: &mut DeBruijnVar<T>, )

Called when finished visiting a $ty (unless visit_$ty is overriden).

fn visit_by_val<T: AstVisitable>( self, x: &mut T, ) -> ControlFlow<Self::Break, Self>

Convenience alias for method chaining.

fn visit_by_val_infallible<T: AstVisitable>(self, x: &mut T) -> Self

where Self: Visitor<Break = Infallible> + Sized,

Convenience when the visitor does not return early.

fn visit_inner<T>(&mut self, x: &mut T) -> ControlFlow<Self::Break>
