Trait Layer

pub trait Layer: Default {
    // Required methods
    fn with_bounds(bounds: Rectangle) -> Self;
    fn flush(&mut self);
    fn resize(&mut self, bounds: Rectangle);
    fn reset(&mut self);
}

A layer of graphical primitives.

Layers normally dictate a set of primitives that are rendered in a specific order.

Required Methods

fn with_bounds(bounds: Rectangle) -> Self

Creates a new Layer with the given bounds.

fn flush(&mut self)

Flushes and settles any pending group of primitives in the Layer.

This will be called when a Layer is finished. It allows layers to efficiently record primitives together and defer grouping until the end.

fn resize(&mut self, bounds: Rectangle)

Resizes the Layer to the given bounds.

fn reset(&mut self)

Clears all the layers contents and resets its bounds.

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.
