Enum Layer 

pub enum Layer {
    Relative(i16),
    Overlay,
    OverlayLevel(u8),
}

The painting layer of an element, controlling what it draws on top of.

Converts from an i16, which becomes a Layer::Relative offset.

Variants

Relative(i16)

Relative layer to the parent’s layer. 0 (the default) keeps the normal stacking order. Negative values move behind siblings and positive values in front.

Overlay

Adds a big layer jump relative to the parents layer. You may stack multiple overlays on top of each other.

OverlayLevel(u8)

Paint on a specific, numbered overlay level, regardless of the parent’s layer. There are up to 16 levels you can use, anything above will be capped at 16.

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 From<i16> for Layer

fn from(value: i16) -> Self

Converts to this type from the input 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 StructuralPartialEq for Layer
