Struct Point2 

pub struct Point2 { /* private fields */ }

A two-dimensional point.

Implementations

impl Point2

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

Constructs a point from Real coordinates.

pub fn from_values<X, Y>(x: X, y: Y) -> Self

where X: Into<Real>, Y: Into<Real>,

Constructs a point from values convertible into Real coordinates.

pub const fn x(&self) -> &Real

Returns the x coordinate.

pub const fn y(&self) -> &Real

Returns the y coordinate.

pub fn delta_from(&self, other: &Self) -> (Real, Real)

Returns self - other as a coordinate pair.

pub fn distance_squared(&self, other: &Self) -> Real

Returns squared Euclidean distance to another point.

pub fn lerp(&self, other: &Self, t: Real) -> Self

Linearly interpolates between two points.

pub fn translated(&self, dx: Real, dy: Real) -> Self

Translates the point by the given Real delta.

pub fn structural_facts(&self) -> Point2Facts

Returns conservative structural facts for this point’s coordinates.

The facts expose exact-rational schedule eligibility and symbolic dependency families without exposing scalar internals. They are intended for object-level dispatch in the style described by Yap, “Towards Exact Geometric Computation,” Computational Geometry 7.1-2 (1997).

impl Point2

pub fn transform_similarity(&self, transform: &Similarity2) -> Self

Applies a certified planar similarity transform.

Trait Implementations

impl Clone for Point2

fn clone(&self) -> Point2

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Point2

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

Formats the value using the given formatter.

impl PartialEq for Point2

fn eq(&self, other: &Point2) -> 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.
