Struct Point

#[repr(C)]
pub struct Point {
    pub x: f32,
    pub y: f32,
}

A point.

Doesn’t guarantee to be finite.

Fields

x: f32

y: f32

Implementations

impl Point

pub fn from_xy(x: f32, y: f32) -> Point

Creates a new Point.

pub fn from_f32x2(r: f32x2) -> Point

Creates a new Point from f32x2.

pub fn to_f32x2(&self) -> f32x2

Converts a Point into a f32x2.

pub fn zero() -> Point

Creates a point at 0x0 position.

pub fn is_zero(&self) -> bool

Returns true if x and y are both zero.

pub fn is_finite(&self) -> bool

Returns true if both x and y are measurable values.

Both values are other than infinities and NaN.

pub fn normalize(&mut self) -> bool

Scales (fX, fY) so that length() returns one, while preserving ratio of fX to fY, if possible.

If prior length is nearly zero, sets vector to (0, 0) and returns false; otherwise returns true.

pub fn set_normalize(&mut self, x: f32, y: f32) -> bool

Sets vector to (x, y) scaled so length() returns one, and so that (x, y) is proportional to (x, y).

If (x, y) length is nearly zero, sets vector to (0, 0) and returns false; otherwise returns true.

pub fn length(&self) -> f32

Returns the Euclidean distance from origin.

pub fn set_length(&mut self, length: f32) -> bool

Scales vector so that distanceToOrigin() returns length, if possible.

If former length is nearly zero, sets vector to (0, 0) and return false; otherwise returns true.

pub fn set_length_from(&mut self, x: f32, y: f32, length: f32) -> bool

Sets vector to (x, y) scaled to length, if possible.

If former length is nearly zero, sets vector to (0, 0) and return false; otherwise returns true.

pub fn distance(&self, other: Point) -> f32

Returns the Euclidean distance from origin.

pub fn dot(&self, other: Point) -> f32

Returns the dot product of two points.

pub fn cross(&self, other: Point) -> f32

Returns the cross product of vector and vec.

Vector and vec form three-dimensional vectors with z-axis value equal to zero. The cross product is a three-dimensional vector with x-axis and y-axis values equal to zero. The cross product z-axis component is returned.

pub fn scale(&mut self, scale: f32)

Scales Point in-place by scale.

Trait Implementations

impl Add for Point

type Output = Point

The resulting type after applying the + operator.

fn add(self, other: Point) -> <Point as Add>::Output

Performs the + operation.

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

Formats the value using the given formatter.

impl Default for Point

fn default() -> Point

Returns the “default value” for a type.

impl From<(f32, f32)> for Point

fn from(v: (f32, f32)) -> Point
