Struct Vector 

pub struct Vector { /* private fields */ }

An immutable vector in 2-space. This represents size and direction. See Point

Implementations

impl Vector

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

pub fn up() -> Self

pub fn down() -> Self

pub fn zero() -> Self

pub fn norm(&self) -> f64

pub fn x(&self) -> f64

pub fn y(&self) -> f64

pub fn rotate(&self, degrees: f64) -> Self

Returns a vector rotated by the given degrees.

Here is an example of how to make use of rotations. Note that rust has built in support for converting between degrees and radians. See f64::to_radians and f64::to_degrees.

use rusty_systems::geometry::Vector;
let up = Vector::up();
let left = up.rotate(90.0);

assert!((up - Vector::new(0.0, 1.0)).norm() < 0.001);   // The up vector is (0, 1)
assert!((left - Vector::new(-1.0, 0.0)).norm() < 0.001) // rotated by 90º, it points (-1, 0)

Trait Implementations

impl Add<Vector> for Path

Offset all points in the path by the given vector.

type Output = Path

The resulting type after applying the + operator.

fn add(self, rhs: Vector) -> Self::Output

Performs the + operation.

impl Add<Vector> for Point

type Output = Point

The resulting type after applying the + operator.

fn add(self, rhs: Vector) -> Self::Output

Performs the + operation.

impl Add for Vector

type Output = Vector

The resulting type after applying the + operator.

fn add(self, rhs: Self) -> Self::Output

Performs the + operation.

impl Clone for Vector

fn clone(&self) -> Vector

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Vector

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

Formats the value using the given formatter.

impl Default for Vector

fn default() -> Self

Returns the “default value” for a type.

impl Display for Vector

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

Formats the value using the given formatter.

impl From<Point> for Vector

fn from(value: Point) -> Self

Converts to this type from the input type.

impl From<Vector> for Point

fn from(value: Vector) -> Self

Converts to this type from the input type.

impl Neg for Vector

type Output = Vector

The resulting type after applying the - operator.

fn neg(self) -> Self::Output

Performs the unary - operation.

impl PartialEq for Vector

fn eq(&self, other: &Vector) -> 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 Sub<Vector> for Point

type Output = Point

The resulting type after applying the - operator.

fn sub(self, rhs: Vector) -> Self::Output

Performs the - operation.

impl Sub for Vector

type Output = Vector

The resulting type after applying the - operator.

fn sub(self, rhs: Self) -> Self::Output

Performs the - operation.

impl Copy for Vector

impl StructuralPartialEq for Vector
