Struct bevy_render::view::visibility::RenderLayers

source ·
pub struct RenderLayers(/* private fields */);
Expand description

Describes which rendering layers an entity belongs to.

Cameras with this component will only render entities with intersecting layers.

Entities may belong to one or more layers, or no layer at all.

The Default instance of RenderLayers contains layer 0, the first layer.

An entity with this component without any layers is invisible.

Entities without this component belong to layer 0.

Implementations§

source§

impl RenderLayers

source

pub const fn layer(n: Layer) -> Self

Create a new RenderLayers belonging to the given layer.

source

pub const fn none() -> Self

Create a new RenderLayers that belongs to no layers.

This is distinct from RenderLayers::default, which belongs to the first layer.

source

pub fn from_layers(layers: &[Layer]) -> Self

Create a RenderLayers from a list of layers.

source

pub fn with(self, layer: Layer) -> Self

Add the given layer.

This may be called multiple times to allow an entity to belong to multiple rendering layers.

source

pub fn without(self, layer: Layer) -> Self

Removes the given rendering layer.

source

pub fn iter(&self) -> impl Iterator<Item = Layer> + '_

Get an iterator of the layers.

source

pub fn intersects(&self, other: &RenderLayers) -> bool

Determine if a RenderLayers intersects another.

RenderLayerss intersect if they share any common layers.

A RenderLayers with no layers will not match any other RenderLayers, even another with no layers.

source

pub fn bits(&self) -> &[u64]

get the bitmask representation of the contained layers

source

pub fn intersection(&self, other: &Self) -> Self

Returns the set of layers shared by two instances of RenderLayers.

This corresponds to the self & other operation.

source

pub fn union(&self, other: &Self) -> Self

Returns all layers included in either instance of RenderLayers.

This corresponds to the self | other operation.

source

pub fn symmetric_difference(&self, other: &Self) -> Self

Returns all layers included in exactly one of the instances of RenderLayers.

This corresponds to the “exclusive or” (XOR) operation: self ^ other.
