Trait Visitable 

pub(crate) trait Visitable<'a, V: Visitor<'a>> {
    type Extra: Copy;

    // Required method
    fn visit(&'a self, visitor: &mut V, extra: Self::Extra) -> V::Result;
}

Required Associated Types

type Extra: Copy

Required Methods

fn visit(&'a self, visitor: &mut V, extra: Self::Extra) -> V::Result

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
