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<T> From<Id<T>> for Array<T>

An Id<T> is an Array<T> with a length of 1.

fn from(id: Id<T>) -> Array<T>

Converts to this type from the input type.

impl<T> From<u32> for Id<T>

fn from(value: u32) -> Id<T>

Converts to this type from the input type.

impl<T> From<usize> for Id<T>

fn from(value: usize) -> Id<T>

Converts to this type from the input type.

impl<T> Hash for Id<T>

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

where H: Hasher,

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<T> Ord for Id<T>

fn cmp(&self, other: &Id<T>) -> 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<T> PartialEq for Id<T>

fn eq(&self, other: &Id<T>) -> 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<T> PartialOrd for Id<T>

fn partial_cmp(&self, other: &Id<T>) -> 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.

impl<T> SlabItem for Id<T>

where T: Any,

const SLAB_SIZE: usize = 1usize

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

fn read_slab(index: usize, slab: &[u32]) -> Id<T>

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.
