Struct Light 

#[repr(C)]
pub struct Light {
    pub light_type: LightStyle,
    pub index: u32,
    pub transform: Id<Transform>,
}

A type-erased linked-list-of-lights that is used as a slab pointer to any light type.

Fields

light_type: LightStyle

index: u32

transform: Id<Transform>

Implementations

impl Light

pub fn into_directional_id(self) -> Id<DirectionalLight>

pub fn into_spot_id(self) -> Id<SpotLight>

pub fn into_point_id(self) -> Id<PointLight>

Trait Implementations

impl Clone for Light

fn clone(&self) -> Light

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Light

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

Formats the value using the given formatter.

impl Default for Light

fn default() -> Self

Returns the “default value” for a type.

impl From<Id<DirectionalLight>> for Light

fn from(id: Id<DirectionalLight>) -> Self

Converts to this type from the input type.

impl From<Id<PointLight>> for Light

fn from(id: Id<PointLight>) -> Self

Converts to this type from the input type.

impl From<Id<SpotLight>> for Light

fn from(id: Id<SpotLight>) -> Self

Converts to this type from the input type.

impl PartialEq for Light

fn eq(&self, other: &Light) -> 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 SlabItem for Light

where LightStyle: SlabItem, u32: SlabItem, Id<Transform>: SlabItem,

const SLAB_SIZE: usize = 3usize

The number of u32s this type occupies in a slab of &[u32].

fn read_slab(index: usize, slab: &[u32]) -> Self

Read the type out of the slab at index.

fn write_slab(&self, index: usize, slab: &mut [u32]) -> usize

Write the type into the slab at starting index and return the new index.
