Expand description

The WebGlRenderingContext class.

The WebGLRenderingContext.UNPACK_COLORSPACE_CONVERSION_WEBGL const.

This API requires the following crate features to be activated: WebGlRenderingContext

source

pub const BROWSER_DEFAULT_WEBGL: u32

The WebGLRenderingContext.BROWSER_DEFAULT_WEBGL const.

The valueOf() method returns the primitive value of the specified object.

Tests whether this JS value is a JS string.

source

pub fn as_string(&self) -> Option<String>

If this JS value is a string value, this function copies the JS string value into wasm linear memory, encoded as UTF-8, and returns it as a Rust String.

To avoid the copying and re-encoding, consider the JsString::try_from() function from js-sys instead.

If this JS value is not an instance of a string or if it’s not valid utf-8 then this returns None.

JavaScript strings in general are encoded as UTF-16, but Rust strings are encoded as UTF-8. This can cause the Rust string to look a bit different than the JS string sometimes. For more details see the documentation about the str type which contains a few caveats about the encodings.

source

pub fn as_bool(&self) -> Option<bool>

Returns the bool value of this JS value if it’s an instance of a boolean.

Tests whether the value is “truthy”.

source

Applies the unary + JS operator on a JsValue. Can throw.

Returns a copy of the value. Read more

impl Deref for WebGlRenderingContext

type Target = Object

The resulting type after dereferencing.

This method tests for !=.

source

impl RefFromWasmAbi for WebGlRenderingContext

type Abi = <JsValue as RefFromWasmAbi>::Abi

The wasm ABI type references to Self are recovered from.

type Anchor = ManuallyDrop<WebGlRenderingContext>

The type that holds the reference to Self for the duration of the invocation of the function that has an &Self parameter. This is required to ensure that the lifetimes don’t persist beyond one function call, and so that they remain anonymous. Read more
