Enum i_slint_core::api::GraphicsAPI

#[non_exhaustive]
pub enum GraphicsAPI<'a> {
    NativeOpenGL {
        get_proc_address: &'a dyn Fn(&str) -> *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

Fields

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

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

The rendering is done using OpenGL.

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.

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

Trait Implementations

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

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for GraphicsAPI<'a>

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

Formats the value using the given formatter.
