}Expand description
This trait is implemented for every visiting traversal. There is a visit method defined for every type of interest. Each such method has a default that recurses into the type’s fields in a non-custom fashion.

Provided Methods§
fn visit_binder<T>(&mut self, t: &Binder<I, T>) -> Self::Resultwhere
T: TypeVisitable<I>,
fn visit_ty(&mut self, t: <I as Interner>::Ty) -> Self::Result
fn visit_region(&mut self, r: <I as Interner>::Region) -> Self::Result

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.
