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,
    },
    WGPU24 {
        instance: Instance,
        device: Device,
        queue: Queue,
    },
}

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.

WGPU24

The rendering is based on WGPU 24.x. Use the provided fields to submit commits to the provided WGPU command queue.

Note: This function is behind the unstable-wgpu-24 feature flag and may be removed or changed in future minor releases, as new major WGPU releases become available.

See also the slint::wgpu_24 module.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

instance: Instance

The WGPU instance used for rendering.

device: Device

The WGPU device used for rendering.

queue: Queue

The WGPU queue for used for command submission.

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.
