Struct ComputedScrollbarStyle 

pub struct ComputedScrollbarStyle {
    pub width: Option<LayoutWidth>,
    pub thumb_color: Option<ColorU>,
    pub track_color: Option<ColorU>,
    pub handle_width: Option<f32>,
    pub handle_radius: Option<f32>,
}

The final, resolved style for a scrollbar, after considering both standard and -webkit- properties. This struct is intended for use by the layout engine.

Fields

width: Option<LayoutWidth>

The width of the scrollbar. None signifies scrollbar-width: none.

thumb_color: Option<ColorU>

The color of the scrollbar thumb. None means use UA default.

track_color: Option<ColorU>

The color of the scrollbar track. None means use UA default.

handle_width: Option<f32>

How wide the HANDLE is, in logical px — which is not the same thing as how wide the scrollbar is.

Breeze draws a 6px handle centred in a 21px groove; Adwaita and macOS also inset theirs. Deriving the handle from the groove instead produced a handle that fills the whole track, which is why an azul scrollbar read as a fat pill next to a native one. None = fill the groove (the previous behaviour).

handle_radius: Option<f32>

The handle’s corner radius in logical px. None = half the handle width (a capsule), which is right for Breeze and Adwaita but wrong for the square handles of older/classic styles — so it is a value the platform gets to state rather than one the renderer assumes.
