cursive::wrap_impl

macro_rules! wrap_impl {
    (&self.$v:ident) => { ... };
    (self.$v:ident) => { ... };
}

Convenient macro to implement the ViewWrapper trait.

Examples

If the wrapped view is in a box, just name it in the macro:

struct BoxFooView {
    content: Box<View>,
}

impl ViewWrapper for BoxFooView {
    wrap_impl!(self.content);
}

If the content is directly a view, reference it:

struct FooView<T: View> {
    view: T,
}

impl <T: View> ViewWrapper for FooView<T> {
    wrap_impl!(&self.view);
}
