Struct WindowSize 

pub struct WindowSize {
    pub width_dp: f32,
    pub height_dp: f32,
    pub class: WindowSizeClass,
    pub height_class: WindowHeightClass,
}

The window’s size, as the Renderer last measured it.

width_dp and height_dp are density-independent pixels, the same unit gesture coordinates use. They are the measurements taken at the moment the class last changed, not a value that follows every pixel of a drag: a size that changed every layout pass would run the runtime every layout pass.

Fields

width_dp: f32

height_dp: f32

class: WindowSizeClass

height_class: WindowHeightClass

Implementations

impl WindowSize

pub const fn new( width_dp: f32, height_dp: f32, class: WindowSizeClass, height_class: WindowHeightClass, ) -> Self

pub fn is_compact(&self) -> bool

Phone-shaped: narrower than 600dp. One column.

pub fn is_medium(&self) -> bool

Tablet-shaped: 600dp to 840dp.

pub fn is_expanded(&self) -> bool

Desktop-shaped: 840dp and wider. Room for a permanent sidebar.

pub fn is_short(&self) -> bool

Short: under 480dp tall. A phone lying on its side is the usual one, and a column of stacked sections is what has to fold there.

pub fn is_medium_height(&self) -> bool

The ordinary height: 480dp to 900dp.

pub fn is_tall(&self) -> bool

Tall: 900dp and more. A portrait tablet, or a window someone stretched.

Trait Implementations

impl Clone for WindowSize

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for WindowSize

impl Debug for WindowSize

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

Formats the value using the given formatter.

impl Default for WindowSize

fn default() -> Self

What a component sees before the Renderer has measured anything.

Compact rather than a wider guess: a one-column layout is usable at any width, so the single render that happens before the first measurement arrives is never broken, only narrower than it needs to be.

impl PartialEq for WindowSize

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

Equality operator ==.

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

Inequality operator !=.
