Enum Layer 

#[non_exhaustive]
pub enum Layer {
    Invalid,
    Background,
    Canvas,
    Widget,
    Mdi,
    Popup,
    Overlay,
    Window,
}

Describes the layer of a component

These enumerated “layer values” are used when determining which UI rendering layer a component is drawn into, which can help in making determinations of when components occlude one another.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Invalid

The object does not have a layer

Background

This layer is reserved for the desktop background

Canvas

This layer is used for Canvas components

Widget

This layer is normally used for components

Mdi

This layer is used for layered components

Popup

This layer is used for popup components, such as menus

Overlay

This layer is reserved for future use.

Window

This layer is used for toplevel windows.
