Struct MapAny 

pub struct MapAny<A, W: Widget<Data = ()>> {
    pub inner: W,
    /* private fields */
}

Map any input data to ()

This is a generic data-mapping widget-wrapper with fixed () input data type.

This struct is a thin wrapper around the inner widget without its own Id. It supports Deref and DerefMut to the inner widget.

Fields

inner: W

The inner widget
