Struct cvar::VisitMut

pub struct VisitMut<F: FnMut(&mut dyn FnMut(&mut dyn INode))>(pub F);

Node visitor from closure.

The visitor trait IVisit requires a struct type to be implemented. This wrapper type allows a visitor to be created out of a closure instead.

let mut value = 0;

let mut visitor = cvar::VisitMut(|f| {
    f(&mut cvar::Property("value", "description", &mut value, 0));
});

let _ = cvar::console::set(&mut visitor, "value", "42");
assert_eq!(value, 42);
