Trait Walk 

pub trait Walk<'a, A: AstTypes> {
    // Required method
    fn visit_in<V: Visit<'a, A> + ?Sized>(
        &'a self,
        v: &mut V,
    ) -> Result<(), V::Error>;

    // Provided method
    fn children<V: Visit<'a, A> + ?Sized>(
        &'a self,
        _v: &mut V,
    ) -> Result<(), V::Error> { ... }
}

Required Methods

fn visit_in<V: Visit<'a, A> + ?Sized>( &'a self, v: &mut V, ) -> Result<(), V::Error>

Provided Methods

fn children<V: Visit<'a, A> + ?Sized>( &'a self, _v: &mut V, ) -> Result<(), V::Error>

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.
