Module parser::visitor

The visitor module for the AST.

The visitor is based on an Enum over every AST node.

Example usages:

struct MyVisitor<'a, 'f> {
    some_data: Vec<u32>,
}

impl<'a, 'f> MyVisitor<'a, 'f> {
    fn new() -> Self {
        Self {
            some_data: Vec::new(),
        }
    }

    fn do_visit(&mut self, node: &NodeKind<'a, 'f>) {
        use self::NodeKind::*;
        node.for_each_child(&mut |child| {
            match child {
                AST(_) => (),
                Program(_) => {
                    // some code
                }
                _ => (),
            }

            self.do_visit(&child)
        })
    }
}
