Enum RenderingState

#[non_exhaustive]
#[repr(u8)]
pub enum RenderingState {
    RenderingSetup = 0,
    BeforeRendering = 1,
    AfterRendering = 2,
    RenderingTeardown = 3,
}

This enum describes the different rendering states, that will be provided to the parameter of the callback for set_rendering_notifier on the slint::Window.

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.

RenderingSetup = 0

The window has been created and the graphics adapter/context initialized. When OpenGL is used for rendering, the context will be current.

BeforeRendering = 1

The scene of items is about to be rendered. When OpenGL is used for rendering, the context will be current.

AfterRendering = 2

The scene of items was rendered, but the back buffer was not sent for display presentation yet (for example GL swap buffers). When OpenGL is used for rendering, the context will be current.

RenderingTeardown = 3

The window will be destroyed and/or graphics resources need to be released due to other constraints.
