Trait Implementations

impl<D: DomTypes> DomObject for GPUBuffer<D>

type ReflectorType = ()

fn reflector(&self) -> &Reflector<Self::ReflectorType>

Returns the receiver’s reflector.

impl<D: DomTypes> Drop for GPUBuffer<D>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl<D: DomTypes> HasParent for GPUBuffer<D>

fn as_parent(&self) -> &Reflector

This is used in a type assertion to ensure that the source and webidls agree as to what the parent type is

type Parent = Reflector

impl<D: DomTypes> IDLInterface for GPUBuffer<D>

const PROTO_FIRST: u16 = 371

First prototype ID in the DFS-ordered range for this interface and its descendants.

const PROTO_LAST: u16 = 371

Last prototype ID in the DFS-ordered range for this interface and its descendants.

fn derives(class: &'static DOMClass) -> bool

Returns whether the given DOM class derives that interface.

impl<D> MallocSizeOf for GPUBuffer<D>

where D: MallocSizeOf + DomTypes,

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl<D: DomTypes> MutDomObject for GPUBuffer<D>

unsafe fn init_reflector<Actual>(&self, obj: *mut JSObject)

Initializes the Reflector

unsafe fn init_reflector_without_associated_memory(&self, obj: *mut JSObject)

Initializes the Reflector without recording any associated memory usage.

impl<D: DomTypes> PartialEq for GPUBuffer<D>

fn eq(&self, other: &Self) -> 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<D: DomTypes> ToJSValConvertible for GPUBuffer<D>

fn safe_to_jsval(&self, cx: &mut JSContext, rval: MutableHandleValue<'_>)

Convert self to a JSVal. JSAPI failure causes a panic.
