## Walkable

# Trait Walkable

Source

    pub(crate) trait Walkable<'a, V: Visitor<'a>> {
        // Required method
        fn walk_ref(&'a self, visitor: &mut V) -> V::Result;
    }

## Required Methods§

Source

#### fn walk_ref(&'a self, visitor: &mut V) -> V::Result

## Dyn Compatibility§

This trait is dyn compatible.

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