Struct LightIndex

pub struct LightIndex(/* private fields */);

Index for one of the 8 hardware lights in the lighting environment.

Usually you don’t want to construct one of these directly but use LightEnv::create_light.

Implementations

impl LightIndex

pub fn new(idx: usize) -> Self

Manually create a LightIndex with a specific index

Panics

if idx out of range for the number of lights (>=8)

pub fn as_usize(self) -> usize

Converts the index back into a raw integer.

Trait Implementations

impl Clone for LightIndex

fn clone(&self) -> LightIndex

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Hash for LightIndex

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 PartialEq for LightIndex

fn eq(&self, other: &LightIndex) -> 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.
