Struct CGSize 

#[repr(C)]
pub struct CGSize {
    pub width: f64,
    pub height: f64,
}

CGSize representation

Represents a 2D size with width and height.

Examples

use apple_cf::cg::CGSize;

let size = CGSize::new(1920.0, 1080.0);
assert_eq!(size.aspect_ratio(), 1920.0 / 1080.0);
assert_eq!(size.area(), 1920.0 * 1080.0);

Fields

width: f64

height: f64

Implementations

impl CGSize

pub const fn new(width: f64, height: f64) -> CGSize

Create a new size

Examples

use apple_cf::cg::CGSize;

let size = CGSize::new(800.0, 600.0);
assert_eq!(size.width, 800.0);

pub const fn zero() -> CGSize

Create a zero-sized size

Examples

use apple_cf::cg::CGSize;

let size = CGSize::zero();
assert!(size.is_null());

pub const fn area(&self) -> f64

Get the area (width * height)

pub fn aspect_ratio(&self) -> f64

Get the aspect ratio (width / height)

pub const fn is_square(&self) -> bool

Check if this is a square (width == height) Note: Uses exact comparison, may not work well with computed values

pub fn is_empty(&self) -> bool

Returns whether the size has a non-positive width or height.

pub const fn is_null(&self) -> bool

Check if size is null (both dimensions are zero)

Trait Implementations

impl Clone for CGSize

fn clone(&self) -> CGSize

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CGSize

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

Formats the value using the given formatter.

impl Default for CGSize

fn default() -> CGSize

Returns the “default value” for a type.

impl Display for CGSize

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

Formats the value using the given formatter.

impl Hash for CGSize

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

where H: Hasher,

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 CGSize

fn eq(&self, other: &CGSize) -> 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.
