Enum Layer 

pub enum Layer {
    Background,
    Bottom,
    Top,
    Overlay,
}

Available on crate feature wayland_frontend only.

Available layers for surfaces

These values indicate which layers a surface can be rendered in. They are ordered by z depth, bottom-most first. Traditional shell surfaces will typically be rendered between the bottom and top layers. Fullscreen shell surfaces are typically rendered at the top layer. Multiple surfaces can share a single layer, and ordering within a single layer is undefined.

Variants

Background

The lowest layer, used usualy for wallpapers

Bottom

The layer bellow the windows and above the wallpaper

Top

The layer above the windows and bellow overlay

Overlay

The top layer above all other layers

Trait Implementations

impl Clone for Layer

fn clone(&self) -> Layer

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Layer

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Layer

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Layer

fn eq(&self, other: &Layer) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<WEnum<Layer>> for Layer

type Error = (Error, String)

The type returned in the event of a conversion error.

fn try_from(layer: WEnum<Layer>) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for Layer

impl Eq for Layer

impl StructuralPartialEq for Layer
