Trait Implementations

impl GraphicsContext for WebSysWebGL2Surface

type Backend = WebGL2

Internal type used by the backend to cache, optimize and store data. This roughly represents the GPU data / context a backend implementation needs to work correctly.

fn backend(&mut self) -> &mut Self::Backend

Access the underlying backend.

fn query(&mut self) -> Query<'_, Self::Backend> where
    Self::Backend: Query, 

Access the query API.

fn new_pipeline_gate(&mut self) -> PipelineGate<'_, Self::Backend>

Create a new pipeline gate

fn new_framebuffer<D, CS, DS>(
    &mut self,
    size: <D as Dimensionable>::Size,
    mipmaps: usize,
    sampler: Sampler
) -> Result<Framebuffer<Self::Backend, D, CS, DS>, FramebufferError> where
    D: Dimensionable,
    CS: ColorSlot<Self::Backend, D>,
    DS: DepthStencilSlot<Self::Backend, D>,
    Self::Backend: Framebuffer<D>, 

Create a new framebuffer.

    &mut self,
    ty: StageType,
    src: R
) -> Result<Stage<Self::Backend>, StageError> where
    R: AsRef<str>,
    Self::Backend: Shader, 

Create a new shader stage.

fn new_shader_program<Sem, Out, Uni>(
    &mut self
) -> ProgramBuilder<'_, Self, Sem, Out, Uni> where
    Sem: Semantics,
    Self::Backend: Shader, 

Create a new shader program.

fn new_shader_data<T>(
    &mut self,
    values: impl IntoIterator<Item = T>
) -> Result<ShaderData<Self::Backend, T>, ShaderDataError> where
    Self::Backend: ShaderData<T>,
