    fn state(&self) -> &ScrollingState;

    fn state_mut(&mut self) -> &mut ScrollingState;

Expand description

A horizontally scrolling sequence of 5×5 images.

Scrollables automatically implement Animate.

When a Scrollable also implements Render, the rendered image is the current state of the animation.

Associated Types

The type of the underlying 5×5 images.

Required methods

The number of underlying images.

A ScrollingState indicating the current point in the animation.

A ScrollingState indicating the current point in the animation, as a mutable reference.

A reference to the underlying image at the specified index.

Provided methods

Returns the brightness value for a single LED in the current state.

Use this to implement Render.
