# visit

Automatically generate code for the [Visitor pattern](https://en.wikipedia.org/wiki/Visitor_pattern).

## Usage

```rust

visit! {

    // Automatically generates `Visitor` and `AcceptVisitor` traits

    // The `Visitor` trait will contain `visit_` functions for all items inside of the macro call.

    // The `AcceptVisitor` trait will be implemented automatically for all items.

    #![visitor(name = "Visitor")]

    struct Bar {

        a: Child,

        b: Child,

    }

    struct Child {}

}

struct MyVisitor;

impl Visitor for MyVisitor {

    fn visit_child(&mut self, _child: &Child) {

        // Do something cool

    }

}

```
