use-viewport

Viewport and display context primitives for RustUse UI.

Purpose

use-viewport describes viewport size, class, orientation, density, and display scale. It stays framework-neutral and does not read browser, desktop, or terminal APIs.

Example

use use_viewport::{DisplayScale, ViewportClass, ViewportOrientation, ViewportSize};

let viewport = ViewportSize::new(390, 844);
let scale = DisplayScale::from_milli(1_250);

assert_eq!(viewport.orientation(), ViewportOrientation::Portrait);
assert_eq!(viewport.class(), ViewportClass::Xs);
assert_eq!(scale.milli(), 1_250);

Main types

• ViewportSize
• ViewportClass
• ViewportOrientation
• Density
• DisplayScale

Facade relationship

The use-ui facade exposes this crate as use_ui::viewport when the viewport or full feature is enabled.
