Enum Layer 

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

The layer the surface is rendered on. Multiple surfaces can share a layer, and ordering within a single layer is undefined.

Variants

Background

The background layer, typically used for wallpapers.

Bottom

The bottom layer.

Top

The top layer, typically used for fullscreen windows.

Overlay

The overlay layer, used for surfaces that should always be on top.

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() -> Layer

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 Copy for Layer

impl Eq for Layer
