Source 
pub trait Composition<B: Backend> {
    // Required methods
    fn new(background_color: Color) -> Self;
    fn clear(&mut self);
    fn insert(&mut self, order: Order, layer: Layer<B>);
    fn remove(&mut self, order: Order);
}

Required Methods§

Source

fn new(background_color: Color) -> Self

Creates a composition of ordered layers where the layers with lower index appear on top.

Source

fn clear(&mut self)

Resets composition by removing all layers.

Source

fn insert(&mut self, order: Order, layer: Layer<B>)

Inserts layer into the composition.

Source

fn remove(&mut self, order: Order)

Removes layer from the composition.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
