Enum SizeClass 

pub enum SizeClass {
    Compact,
    Medium,
    Expanded,
}

Re-export: size classes and orientation, so the application can drive its own responsive behaviour. A display-width band.

Thresholds (logical px): Compact < 600, Medium 600–840, Expanded ≥ 840.

Variants

Compact

Phone / narrow window (< 600).

Medium

Portrait tablet / medium window (600–840).

Expanded

Desktop / wide window (≥ 840).

Implementations

impl SizeClass

pub const MEDIUM: f32 = 600.0

Lower bound (inclusive) of the Medium band, in logical px.

pub const EXPANDED: f32 = 840.0

Lower bound (inclusive) of the Expanded band, in logical px.

pub fn from_width(width: f32) -> SizeClass

The class matching a width (logical px).

pub fn from_height(height: f32) -> SizeClass

The class matching a height (logical px), using the same thresholds.

Useful on the vertical axis: a short window (< 600) is Compact in height, which is a cue to hide labels, shrink margins, and so on.

pub fn rank(self) -> u8

Ordinal rank (0 = Compact … 2 = Expanded), handy for comparing bands.

impl Eq for SizeClass

impl Ord for SizeClass

fn cmp(&self, other: &SizeClass) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.
