Provided Methods

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

Convenience alias for method chaining.

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

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

Convenience when the visitor does not return early.

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

where T: for<'s> Drive<'s, AstVisitableWrapper<Self>>,

Visit the contents of x. This calls self.visit() on each field of T. This is available for any type whose contents are all #trait_name.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
