Implementations

impl Point2D

pub fn distance_between_points(&self, point2: Point2D) -> f64

计算两个点之间的欧几里德距离。

参数

• point2: 第二个点的坐标。

返回值

两点之间的欧几里德距离。

示例

use rs_math::graphical::point_2d::Point2D;

let point1 = Point2D { x: 1.0, y: 2.0 };
let point2 = Point2D { x: 4.0, y: 6.0 };
let distance = point1.distance_between_points(point2);
// 验证距离是否符合预期

pub fn rotate(&self, angle: f64) -> Point2D

绕原点逆时针旋转点。

参数

• angle: 旋转角度（弧度）。

返回值

旋转后的点的坐标。

示例

use rs_math::graphical::point_2d::Point2D;

let point = Point2D { x: 3.0, y: 4.0 };
let rotated_point = point.rotate(std::f64::consts::FRAC_PI_2);
// 验证旋转后的坐标是否符合预期

pub fn distance_to(&self, other: &Point2D) -> f64

计算点到另一点的欧几里德距离。

参数

• other: 另一点的坐标。

返回值

两点之间的欧几里德距离。

示例

use rs_math::graphical::point_2d::Point2D;

let point1 = Point2D { x: 1.0, y: 2.0 };
let point2 = Point2D { x: 4.0, y: 6.0 };
let distance = point1.distance_to(&point2);

pub fn add_points(p1: &Point2D, p2: &Point2D) -> Point2D

将两个点的坐标相加，得到新的点。

参数

• p1: 第一个点的坐标。
• p2: 第二个点的坐标。

返回值

两点坐标相加后得到的新点。

示例

use rs_math::graphical::point_2d::Point2D;

let point1 = Point2D { x: 1.0, y: 2.0 };
let point2 = Point2D { x: 3.0, y: 4.0 };
let result = Point2D::add_points(&point1, &point2);

Trait Implementations

impl Clone for Point2D

fn clone(&self) -> Point2D

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Point2D

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

Formats the value using the given formatter.

impl PartialEq for Point2D

fn eq(&self, other: &Point2D) -> 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.
