Enum Layer 

#[repr(u32)]
pub enum Layer {
    Background = 0,
    Bottom = 1,
    Top = 2,
    Overlay = 3,
}

Layer shell layers (bottom to top rendering order).

Surfaces in higher layers are always rendered above surfaces in lower layers. Normal windows sit between Bottom and Top.

Variants

Background = 0

Below all windows (e.g., desktop wallpaper)

Bottom = 1

Below normal windows but above background (e.g., bottom panels)

Top = 2

Above normal windows (e.g., top panels, notification popups)

Overlay = 3

Above everything including fullscreen (e.g., screen lock, OSD)

Implementations

impl Layer

pub fn from_u32(value: u32) -> Option<Self>

Convert a raw protocol value to a Layer.

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 Ord for Layer

fn cmp(&self, other: &Layer) -> Ordering

This method returns an [Ordering] between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

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 PartialOrd for Layer

fn partial_cmp(&self, other: &Layer) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
