Enum WidthClass 

pub enum WidthClass {
    Compact,
    Medium,
    Expanded,
    Large,
    ExtraLarge,
}

How wide a window is, in coarse buckets (docs/size-classes.md).

The breakpoints are Android’s window size classes, in density-independent points, and they are used verbatim on every backend rather than per-platform. One table means one answer: a 700pt window is WidthClass::Medium on a Mac, in a browser, and on a tablet, so an app that lays out from the class gets the same layout at the same size everywhere. Apple publishes only two buckets (compact/regular); those map onto this table rather than replacing it, with WidthClass::Compact the compact one and everything above it regular.

Variants

Compact

< 600dp: a phone in portrait. One pane at a time.

Medium

600–839dp: a tablet in portrait, a narrow desktop window.

Expanded

840–1199dp: a tablet in landscape, a typical desktop window.

Large

1200–1599dp: a large desktop window.

ExtraLarge

≥ 1600dp: a maximized window on a big display.
