Enum GraphicsAPI 

#[non_exhaustive]
pub enum GraphicsAPI<'a> {
    NativeOpenGL {
        get_proc_address: &'a dyn Fn(&CStr) -> *const c_void,
    },
    WebGL {
        canvas_element_id: &'a str,
        context_type: &'a str,
    },
}

This enum describes a low-level access to specific graphics APIs used by the renderer.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NativeOpenGL

The rendering is done using OpenGL.

Fields

get_proc_address: &'a dyn Fn(&CStr) -> *const c_void

Use this function pointer to obtain access to the OpenGL implementation - similar to eglGetProcAddress.

WebGL

The rendering is done on a HTML Canvas element using WebGL.

Fields

canvas_element_id: &'a str

The DOM element id of the HTML Canvas element used for rendering.

context_type: &'a str

The drawing context type used on the HTML Canvas element for rendering. This is the argument to the getContext function on the HTML Canvas element.

Trait Implementations

impl<'a> Clone for GraphicsAPI<'a>

fn clone(&self) -> GraphicsAPI<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GraphicsAPI<'_>

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

Formats the value using the given formatter.
