Struct flo_canvas::LayerId

pub struct LayerId(pub u64);

Identifier of a canvas layer

Layers make it possible to re-draw part of a design without affecting the rest, which is particularly useful for applications where different parts of the application are responsible for drawing different parts of the canvas.

Layer rendering are usually cached, so they are also a good way to reduce the amount of time required to do a redraw.

If a layer is cleared, other entities (such as sprites) are not affected, whereas ClearCanvas will remove all entities from the canvas.
