Struct WindowSizeClass 

pub struct WindowSizeClass {
    pub width: WidthClass,
    pub height: HeightClass,
}

Snapshot of the current window’s size category.

The LayoutEngine updates the WindowSizeClass default local every time the window is resized, so UI can read it via window_size_class() during composition.

Fields

width: WidthClass

height: HeightClass

Implementations

impl WindowSizeClass

pub fn is_expanded_width(&self) -> bool

true when there is enough horizontal space for multi-pane layouts.

pub fn is_at_least_medium_width(&self) -> bool

true when there is enough horizontal space for a two-pane layout (list + detail). Per M3 this is Medium or wider.

Trait Implementations

impl Clone for WindowSizeClass

fn clone(&self) -> WindowSizeClass

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for WindowSizeClass

impl Debug for WindowSizeClass

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for WindowSizeClass

fn default() -> WindowSizeClass

Returns the “default value” for a type.

impl Eq for WindowSizeClass

impl Hash for WindowSizeClass

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for WindowSizeClass

fn eq(&self, other: &WindowSizeClass) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
