Required methods

fn view<G, R>(&mut self, data: T, context: ViewContext<R>, grid: &mut G) where
    G: ViewGrid,
    R: ViewTransformRgb24, 

Update the cells in grid to describe how a type should be rendered. This mutably borrows self to allow the view to contain buffers/caches which are updated during rendering.

Provided methods

fn visible_bounds<R>(&mut self, data: T, context: ViewContext<R>) -> Size where
    R: ViewTransformRgb24, 

Return the size of the visible component of the element without rendering it. By default this is the current context size.

fn view_reporting_intended_size<G, R>(
    &mut self,
    data: T,
    context: ViewContext<R>,
    grid: &mut G
) -> Size where
    G: ViewGrid,
    R: ViewTransformRgb24, 

Render an element and return the size that the element, regardless of the size of the visible component of the element. This allows decorators to know the size of the output of a view they are decorating. By default this calls view keeping track of the maximum x and y components of the relative coords of cells which are set in grid.
