Trait Visit

pub trait Visit<N: ?Sized> {
    // Provided method
    fn visit<'n, D>(visitor: Visitor<'_, 'n, D, Self, N>, _node: &'n N)
       where D: Direct<Self, N> + ?Sized { ... }
}

The action to be performed when visiting a node of type N. This trait must be implemented for all node types in the input, even if the visitor has no special handling for that type.

Provided Methods

fn visit<'n, D>(visitor: Visitor<'_, 'n, D, Self, N>, _node: &'n N)

where D: Direct<Self, N> + ?Sized,

Performs the visiting action. The default implementation simply calls Visitor::visit(visitor), which returns control to the Direct implementation to continue to further sub-nodes. If you wish to skip sub-nodes, simply omit this call from your implementation.

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.
