Struct rerun::external::eframe::egui_wgpu::wgpu::rwh::WebOffscreenCanvasWindowHandle

#[non_exhaustive]
pub struct WebOffscreenCanvasWindowHandle {
    pub obj: NonNull<c_void>,
}

Raw window handle for a Web offscreen canvas registered via wasm-bindgen.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

obj: NonNull<c_void>

A pointer to the JsValue of an OffscreenCanvas.

Note: This uses c_void to avoid depending on wasm-bindgen directly.

Implementations

impl WebOffscreenCanvasWindowHandle

pub fn new(obj: NonNull<c_void>) -> WebOffscreenCanvasWindowHandle

Create a new handle from a pointer to an OffscreenCanvas.

Example

let canvas: &OffscreenCanvas;
let value: &JsValue = &canvas; // Deref to `JsValue`
let obj: NonNull<c_void> = NonNull::from(value).cast();
let mut handle = WebOffscreenCanvasWindowHandle::new(obj);

Trait Implementations

impl Clone for WebOffscreenCanvasWindowHandle

fn clone(&self) -> WebOffscreenCanvasWindowHandle

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WebOffscreenCanvasWindowHandle

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

Formats the value using the given formatter.

impl From<WebOffscreenCanvasWindowHandle> for RawWindowHandle

fn from(value: WebOffscreenCanvasWindowHandle) -> RawWindowHandle

Converts to this type from the input type.

impl Hash for WebOffscreenCanvasWindowHandle

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 PartialEq for WebOffscreenCanvasWindowHandle

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