Struct rustjs::deno_webgpu::wgpu_core::id::Id

pub struct Id<T>(/* private fields */);

An identifier for a wgpu object.

An Id<T> value identifies a value stored in a Global’s Hub’s Storage. Storage implements Index and IndexMut, accepting Id values as indices.

Note on Id typing

You might assume that an Id<T> can only be used to retrieve a resource of type T, but that is not quite the case. The id types in wgpu-core’s public API (TextureId, for example) can refer to resources belonging to any backend, but the corresponding resource types (Texture<A>, for example) are always parameterized by a specific backend A.

So the T in Id<T> is usually a resource type like Texture<Empty>, where Empty is the wgpu_hal dummy back end. These empty types are never actually used, beyond just making sure you access each Storage with the right kind of identifier. The members of Hub<A> pair up each X<Empty> type with the resource type X<A>, for some specific backend A.

Implementations

impl<T> Id<T>

pub unsafe fn from_raw(raw: NonZero<u64>) -> Id<T>

Safety

The raw id must be valid for the type.

pub fn backend(self) -> Backend

Trait Implementations

fn clone(&self) -> Id<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Debug for Id<T>

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

Formats the value using the given formatter.

impl<'de, T> Deserialize<'de> for Id<T>

fn deserialize<__D>( __deserializer: __D, ) -> Result<Id<T>, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T> From<SerialId> for Id<T>

fn from(id: SerialId) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl<T> PartialEq for Id<T>

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

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool
