Enum Vibrancy 

pub enum Vibrancy {
    Auto,
    On,
    Off,
}

Whether the window composites translucent — AppKit’s vibrancy.

Three-valued rather than a bool because the honest answer depends on the appearance, and the appearance moves under the app: the OS switches at sunset. A bool would have to be rewritten by whoever noticed, and nothing outside this crate is told when a palette is installed.

Variants

Auto

Frost where the palette is built for it, which is dark alone.

Light’s glass tokens sit near 85% opacity — see Theme::glass_overlay, Theme::card_glass_bg and Theme::input_glass_bg, each tuned there because a translucent white tint left text ghosting over whatever sat behind it. Light pays for the blur and shows almost none of it, so it is not asked for unless an app says so.

On

Frost in both appearances. What an app asks for when it has tuned its own light palette to carry one.

Off

Opaque in both. What a Reduce-transparency switch sets.

Implementations

impl Vibrancy

pub fn on(self, appearance: Appearance) -> bool

Whether to composite translucent for appearance.

The platform gate rides on Vibrancy::Auto rather than on the caller: off macOS there is no compositor-blur guarantee, and a window that is merely transparent shows raw desktop through the sidebar. An app that knows its compositor says Vibrancy::On and gets it.
