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,

}

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.

#[non_exhaustive]

WGPU26

The rendering is based on WGPU 26.x. Use the provided fields to submit commits to the provided WGPU command queue.

Note: This function is behind the unstable-wgpu-26 feature flag and may be removed or changed in future minor releases, as new major WGPU releases become available.

See also the slint::wgpu_26 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.

#[non_exhaustive]

WGPU27

The rendering is based on WGPU 27.x. Use the provided fields to submit commits to the provided WGPU command queue.

Note: This function is behind the unstable-wgpu-27 feature flag and may be removed or changed in future minor releases, as new major WGPU releases become available.

See also the slint::wgpu_27 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.
