Struct SurfmanRenderingContext 

struct SurfmanRenderingContext {
    gleam_gl: Rc<dyn Gl>,
    glow_gl: Arc<Context>,
    device: RefCell<Device>,
    context: RefCell<Context>,
}

A rendering context that uses the Surfman library to create and manage the OpenGL context and surface. This struct provides the default implementation of the RenderingContext trait, handling the creation, management, and destruction of the rendering context and its associated resources.

The SurfmanRenderingContext struct encapsulates the necessary data and methods to interact with the Surfman library, including creating surfaces, binding surfaces, resizing surfaces, presenting rendered frames, and managing the OpenGL context state.

Fields

gleam_gl: Rc<dyn Gl>

glow_gl: Arc<Context>

device: RefCell<Device>

context: RefCell<Context>
