Trait cvar::IVisit

pub trait IVisit {
    fn visit_mut(&mut self, f: &mut dyn FnMut(&mut dyn INode));
}

Node visitor.

The visitor pattern is used to discover child nodes in custom types.

This trait is most commonly required to be implemented by users of this crate.

struct Foo {
    data: i32,
}
impl cvar::IVisit for Foo {
    fn visit_mut(&mut self, f: &mut FnMut(&mut cvar::INode)) {
        // Pass type-erased properties, lists and actions to the closure
        f(&mut cvar::Property("data", "description", &mut self.data, 42));
    }
}

Required methods

fn visit_mut(&mut self, f: &mut dyn FnMut(&mut dyn INode))

Visits the child nodes.

Callers may depend on the particular order in which the nodes are passed to the closure.
