The renderer of a Scrollable.

Your renderer will need to implement this trait before being able to use a Scrollable in your user interface.

Required methods

`fn scrollbar( &self, bounds: Rectangle, content_bounds: Rectangle, offset: u32 ) -> Option<Scrollbar>`

Returns the Scrollbar given the bounds and content bounds of a Scrollable.

`fn draw( &mut self, scrollable: &State, bounds: Rectangle, content_bounds: Rectangle, is_mouse_over: bool, is_mouse_over_scrollbar: bool, scrollbar: Option<Scrollbar>, offset: u32, style: &Self::Style, content: Self::Output ) -> Self::Output`

Draws the Scrollable.

It receives:

the State of the Scrollable
the bounds of the Scrollable widget
the bounds of the Scrollable content
whether the mouse is over the Scrollable or not
whether the mouse is over the Scrollbar or not
a optional Scrollbar to be rendered
the scrolling offset
the drawn content
