Struct WebGlContext 

pub struct WebGlContext { /* private fields */ }

A WebGL context registered with the module.

Implementations

impl WebGlContext

pub fn new( context_id: i32, version: GlVersion, sample_count: i32, stencil_size: i32, ) -> Rc<Self>

Wraps the context with the given id and resolves its entry points.

Trait Implementations

impl IGlContext for WebGlContext

fn version(&self) -> GlVersion

The version of the API the context implements.

fn gl_interface(&self) -> Rc<GlInterface>

The entry points of the context.

fn sample_count(&self) -> i32

The number of samples of the default framebuffer.

fn stencil_size(&self) -> i32

The number of stencil bits of the default framebuffer.

fn make_current(&self) -> Rc<dyn IDisposable>

Makes the context current. Disposing the result restores the previously current context.

fn is_shared_with(&self, _context: &dyn IGlContext) -> bool

Whether the two contexts share their objects.

fn can_create_shared_context(&self) -> bool

Whether create_shared_context is supported.

fn create_shared_context( &self, _preferred_versions: Option<&[GlVersion]>, ) -> Option<Rc<dyn IGlContext>>

Creates a context that shares its objects with this one.

impl IGlSkiaSpecificOptionsFeature for WebGlContext

fn use_native_skia_gr_gl_interface(&self) -> bool

Whether Skia should resolve the OpenGL entry points itself, with the interface native to the platform, instead of through the entry point lookup of the context.

impl IOptionalFeatureProvider for WebGlContext

fn try_get_feature(&self, feature_type: TypeId) -> Option<Rc<dyn Any>>

Queries for an optional feature.

impl IPlatformGraphicsContext for WebGlContext

fn is_lost(&self) -> bool

Whether the context is lost and cannot be used anymore.

fn ensure_current(&self) -> Rc<dyn IDisposable>

Makes the context current. Disposing the result restores the previously current context.

fn dispose(&self)

Releases the context.

fn as_any(&self) -> &dyn Any

Lets the backend recover the concrete context type.
