Struct Circle

#[repr(C)]
pub struct Circle<T> {
    pub center: Point<T>,
    pub radius: T,
}

A circle defined by center and radius.

Fields

center: Point<T>

The center points of the circle.

radius: T

The radius of the circle.

Implementations

impl<T> Circle<T>

where T: Real + Clone,

pub fn new(center: Point<T>, radius: T) -> Self

Create circle with the center and radius.

pub fn with_center(center: Point<T>) -> Self

Change circle center

pub fn with_radius(center: Point<T>, radius: T) -> Self

Change circle radius

pub fn from_1_points(p1: &Point<T>) -> Self

Create circle from center point and unknown radius

pub fn from_2_points(p1: &Point<T>, p2: &Point<T>) -> Self

Create circle from two points on the diameter.

pub fn from_3_points(p1: &Point<T>, p2: &Point<T>, p3: &Point<T>) -> Self

Create circle that intersects the 3 points.

impl<T> Circle<T>

where T: Real,

pub fn contains(&self, point: &Point<T>) -> bool

Checks if the circle contains the given points.

impl<T> Circle<T>

where T: Real + FloatConst,

pub fn area(&self) -> T

Returns the area of the circle.

pub fn perimeter(&self) -> T

Returns the circumference of the circle.

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

Checks if the circle intersects the given circle.

impl<T> Circle<T>

where T: Clone + Real + FloatConst + SampleUniform,

pub fn random_point(&self, rng: impl Rng) -> Point<T>

Trait Implementations

impl<T: Clone> Clone for Circle<T>

fn clone(&self) -> Circle<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Circle<T>

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

Formats the value using the given formatter.

impl<T> Default for Circle<T>

where T: Zero + One,

fn default() -> Self

Returns the “default value” for a type.

impl<'de, T> Deserialize<'de> for Circle<T>

where T: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T: Float> EuclideanDistance<T, Circle<T>> for Point<T>

fn euclidean_distance(&self, rhs: &Circle<T>) -> T

fn euclidean_squared(&self, rhs: &Circle<T>) -> T

It is especially suitable when only the length needs to be compared

impl<T> From<&Point<T>> for Circle<T>

where T: One + Clone,

fn from(point: &Point<T>) -> Self

Converts to this type from the input type.

impl<T: Hash> Hash for Circle<T>

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<T: PartialEq> PartialEq for Circle<T>

fn eq(&self, other: &Circle<T>) -> 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<T> Serialize for Circle<T>

where T: Serialize,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
