Struct Point

pub struct Point {
    pub x: f64,
    pub y: f64,
}

A point in 2-dimensional Euclidian space.

A point represents a position, whereas a vector represents a displacement. That is, the result of subtracting two points is a vector. Moreover, the result of adding/subtracting a vector to/from a point is another point. However, adding two points is not defined. Similarly, whereas a point can be scaled, rotated, and translated, a vector can only be scaled and rotated.

Fields

x: f64

y: f64

Implementations

impl Point

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

Creates a new point with the given coordinates.

pub fn origin() -> Point

Returns the point at the origin.

pub fn to_vector(self) -> Vector

Converts self to a vector.

This is equivalent to subtracting self from the origin.

pub fn lerp(self, other: Point, t: f64) -> Point

Linearly interpolate between self and other with parameter t.

Trait Implementations

impl Add<Vector> for Point

type Output = Point

The resulting type after applying the + operator.

fn add(self, v: Vector) -> Point

Performs the + operation.

impl AddAssign<Vector> for Point

fn add_assign(&mut self, vector: Vector)

Performs the += operation.

impl Clone for Point

fn clone(&self) -> Point

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Point

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

Formats the value using the given formatter.

impl Default for Point

fn default() -> Point

Returns the “default value” for a type.

impl PartialEq for Point

fn eq(&self, other: &Point) -> 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 PartialOrd for Point

fn partial_cmp(&self, other: &Point) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Sub<Vector> for Point

type Output = Point

The resulting type after applying the - operator.

fn sub(self, v: Vector) -> Point

Performs the - operation.

impl Sub for Point

type Output = Vector

The resulting type after applying the - operator.

fn sub(self, other: Point) -> Vector

Performs the - operation.

impl SubAssign<Vector> for Point

fn sub_assign(&mut self, vector: Vector)

Performs the -= operation.

impl Transform for Point

fn transform<T>(self, t: &T) -> Point

where T: Transformation,
