Struct ScrollbarStyle 

pub struct ScrollbarStyle {
    pub thickness: f64,
    pub hover_thickness: f64,
    pub min_thumb: f64,
    pub inset: f64,
    pub fade_delay_ms: f64,
    pub fade_duration_ms: f64,
    pub show: ScrollbarShow,
}

Metrics and visibility of an opt-in scrollbar, handed to ScrollView::scrollbar or ListView::scrollbar (vertical only; no horizontal or CustomScrollView surface takes one). Colors come from the theme (on_surface_variant), with an unthemed fallback.

use frust_widgets::{ScrollView, ScrollbarShow, ScrollbarStyle, scroll_view, text};
let style = ScrollbarStyle::default().show(ScrollbarShow::Always).thickness(4.0);
let view: ScrollView<()> = scroll_view(text("hi")).scrollbar(style);

Idle hold before the fade starts, in ms.

fade_duration_ms: f64

Fade-out length, in ms; reduce_motion or 0 snaps instead.

show: ScrollbarShow
