Expand description

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

Variants (Non-exhaustive)ยง

This enum is marked as 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.
ยง

NativeOpenGL

Fields

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

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

The rendering is done using OpenGL.

ยง

WebGL

Fields

ยงcanvas_element_id: &'a str

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

ยงcontext_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.

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