Struct Point 

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

Defines a point.

Fields

x: f64

The X position.

y: f64

The Y position.

Implementations

impl Point

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

Initializes a new instance of the Point structure.

pub fn distance(value1: Point, value2: Point) -> f64

Computes the Euclidean distance between the two given points.

pub fn parse(s: &str) -> Result<Self, FormatError>

Parses a Point string ("x, y" or "x y").

pub fn equals(&self, other: Point) -> bool

Returns a boolean indicating whether the point is equal to the other given point (bitwise equality of the coordinates is not required: this is ==).

pub fn nearly_equals(&self, other: Point) -> bool

Returns a boolean indicating whether the point is equal to the other given point (numerically, within a relative epsilon).

pub fn transform(&self, transform: Matrix) -> Point

Transforms the point by a matrix.

pub const fn with_x(&self, x: f64) -> Point

Returns a new point with the specified X coordinate.

pub const fn with_y(&self, y: f64) -> Point

Returns a new point with the specified Y coordinate.

pub const fn deconstruct(&self) -> (f64, f64)

Deconstructs the point into its X and Y coordinates.
