Struct CGPoint 

#[repr(C)]
pub struct CGPoint {
    pub x: f64,
    pub y: f64,
}

CGPoint representation

Represents a point in 2D space.

Examples

use apple_cf::cg::CGPoint;

let p1 = CGPoint::new(0.0, 0.0);
let p2 = CGPoint::new(3.0, 4.0);
assert_eq!(p1.distance_to(&p2), 5.0);

Fields

x: f64

y: f64

Implementations

impl CGPoint

pub const fn new(x: f64, y: f64) -> CGPoint

Create a new point

Examples

use apple_cf::cg::CGPoint;

let point = CGPoint::new(100.0, 200.0);
assert_eq!(point.x, 100.0);

pub const fn zero() -> CGPoint

Create a point at origin (0, 0)

Examples

use apple_cf::cg::CGPoint;

let point = CGPoint::zero();
assert!(point.is_zero());

pub const fn is_zero(&self) -> bool

Check if point is at origin (0, 0)

pub fn distance_to(&self, other: &CGPoint) -> f64

Calculate distance to another point

pub const fn distance_squared_to(&self, other: &CGPoint) -> f64

Calculate squared distance to another point (faster than distance_to)

Trait Implementations

impl Clone for CGPoint

fn clone(&self) -> CGPoint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CGPoint

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

Formats the value using the given formatter.

impl Default for CGPoint

fn default() -> CGPoint

Returns the “default value” for a type.

impl Display for CGPoint

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

Formats the value using the given formatter.

impl Hash for CGPoint

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 CGPoint

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

impl Copy for CGPoint

impl Eq for CGPoint
