Struct RenderLayer 

pub struct RenderLayer { /* private fields */ }

Represents the rendering priority layer for draw call ordering.

Higher z-index values are drawn on top of lower values, enabling correct visual layering of game objects.

Implementations

impl RenderLayer

Implements construction methods for RenderLayer.

pub fn create(z_index: i32, visible: bool) -> RenderLayer

Creates a render layer with the given z-index and visibility.

Arguments

• i32 - The z-index determining draw order.
• bool - Whether the layer is visible.

Returns

• RenderLayer - The new render layer.

pub fn background() -> RenderLayer

Creates a background render layer with z-index 0 and visibility enabled.

Returns

• RenderLayer - The background layer.

pub fn foreground() -> RenderLayer

Creates a foreground render layer with a high z-index and visibility enabled.

Returns

• RenderLayer - The foreground layer.

pub fn ui() -> RenderLayer

Creates a UI overlay render layer with the highest z-index and visibility enabled.

Returns

• RenderLayer - The UI overlay layer.

Trait Implementations

impl Clone for RenderLayer

fn clone(&self) -> RenderLayer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for RenderLayer

impl Debug for RenderLayer

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

Formats the value using the given formatter.

impl Default for RenderLayer

fn default() -> RenderLayer

Returns the “default value” for a type.

impl Eq for RenderLayer

impl Hash for RenderLayer

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for RenderLayer

fn cmp(&self, other: &RenderLayer) -> 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 RenderLayer

fn eq(&self, other: &RenderLayer) -> 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 RenderLayer

fn partial_cmp(&self, other: &RenderLayer) -> 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.
