Struct Offset 

pub struct Offset {
    pub dx: f32,
    pub dy: f32,
}

A 2D displacement vector.

Semantically different from Point: a point is a position, an offset is a delta between two positions. Point - Point = Offset, Point + Offset = Point.

Fields

dx: f32

dy: f32

Implementations

impl Offset

pub const ZERO: Self

pub const fn new(dx: f32, dy: f32) -> Self

pub fn length(self) -> f32

Trait Implementations

impl Add<Offset> for Point

type Output = Point

The resulting type after applying the + operator.

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

Performs the + operation.

impl Add for Offset

type Output = Offset

The resulting type after applying the + operator.

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

Performs the + operation.

impl Clone for Offset

fn clone(&self) -> Offset

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Offset

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

Formats the value using the given formatter.

impl Default for Offset

fn default() -> Offset

Returns the “default value” for a type.

impl Neg for Offset

type Output = Offset

The resulting type after applying the - operator.

fn neg(self) -> Self

Performs the unary - operation.

impl PartialEq for Offset

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

type Output = Point

The resulting type after applying the - operator.

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

Performs the - operation.

impl Copy for Offset

impl StructuralPartialEq for Offset
