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.

fn enter_fun_decl(&mut self, x: &FunDecl)

Called when starting to visit a $ty (unless visit_$ty is overriden).

fn exit_fun_decl(&mut self, x: &FunDecl)

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

fn visit_global_decl(&mut self, x: &GlobalDecl) -> ControlFlow<Self::Break>

Overrideable method called when visiting a $ty. When overriding this method, call self.visit_inner(x) to keep recursively visiting the type, or don’t call it if the contents of x should not be visited.

The default implementation calls enter_$ty then visit_inner then exit_$ty.

fn enter_global_decl(&mut self, x: &GlobalDecl)

Called when starting to visit a $ty (unless visit_$ty is overriden).

fn exit_global_decl(&mut self, x: &GlobalDecl)

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

fn visit_type_decl(&mut self, x: &TypeDecl) -> ControlFlow<Self::Break>

Overrideable method called when visiting a $ty. When overriding this method, call self.visit_inner(x) to keep recursively visiting the type, or don’t call it if the contents of x should not be visited.

The default implementation calls enter_$ty then visit_inner then exit_$ty.

fn enter_type_decl(&mut self, x: &TypeDecl)

Called when starting to visit a $ty (unless visit_$ty is overriden).

fn exit_type_decl(&mut self, x: &TypeDecl)

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

fn visit_trait_decl(&mut self, x: &TraitDecl) -> ControlFlow<Self::Break>

Overrideable method called when visiting a $ty. When overriding this method, call self.visit_inner(x) to keep recursively visiting the type, or don’t call it if the contents of x should not be visited.

The default implementation calls enter_$ty then visit_inner then exit_$ty.

fn enter_trait_decl(&mut self, x: &TraitDecl)

Called when starting to visit a $ty (unless visit_$ty is overriden).

fn exit_trait_decl(&mut self, x: &TraitDecl)

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

fn visit_trait_impl(&mut self, x: &TraitImpl) -> ControlFlow<Self::Break>

Overrideable method called when visiting a $ty. When overriding this method, call self.visit_inner(x) to keep recursively visiting the type, or don’t call it if the contents of x should not be visited.

The default implementation calls enter_$ty then visit_inner then exit_$ty.

fn enter_trait_impl(&mut self, x: &TraitImpl)

Called when starting to visit a $ty (unless visit_$ty is overriden).

fn exit_trait_impl(&mut self, x: &TraitImpl)

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

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.
