Struct PhysicalSize 

pub struct PhysicalSize {
    pub width: u32,
    pub height: u32,
}

A size in device pixels.

What the swapchain is created at. See the module docs.

Fields

width: u32

Width in device pixels.

height: u32

Height in device pixels.

Implementations

impl PhysicalSize

pub const fn new(width: u32, height: u32) -> Self

A size of width × height device pixels.

pub const fn is_empty(self) -> bool

Whether either dimension is zero — a minimized or not-yet-configured window.

The frame loop uses this to skip rendering rather than to create an invalid swapchain.

pub const fn area(self) -> u64

Pixel count, as a u64 so a 16K×16K target does not overflow.

pub fn to_logical(self, scale_factor: f64) -> LogicalSize

This size in logical units at scale_factor.

pub fn aspect(self) -> Option<f64>

The aspect ratio as a float, or None for an empty size.
