# Trait rustc_middle::ty::visit::TypeVisitable

source ·

    pub trait TypeVisitable<I>: Debug + Clonewhere
        I: Interner,{
        // Required method
        fn visit_with<V>(&self, visitor: &mut V) -> <V as TypeVisitor<I>>::Result
           where V: TypeVisitor<I>;
    }

Expand description

This trait is implemented for every type that can be visited, providing the skeleton of the traversal.

To implement this conveniently, use the derive macro located in `rustc_macros`.

## Required Methods§

source

#### fn visit_with<V>(&self, visitor: &mut V) -> <V as TypeVisitor<I>>::Result
where V: TypeVisitor<I>,

The entry point for visiting. To visit a value `t` with a visitor `v` call: `t.visit_with(v)`.

For most types, this just traverses the value, calling `visit_with` on each field/element.

For types of interest (such as `Ty`), the implementation of this method that calls a visitor method specifically for that type (such as `V::visit_ty`). This is where control transfers from `TypeVisitable` to `TypeVisitor`.

## Object Safety§

This trait is not object safe.
