Struct Ray2 

pub struct Ray2 { /* private fields */ }

A half-infinite 2D ray.

Implementations

impl Ray2

pub const fn new(origin: Point2, direction: Vector<2>) -> Ray2

Creates a ray without validation.

pub fn try_new( origin: Point2, direction: Vector<2>, ) -> Result<Ray2, GeometryError>

Creates a ray with a finite origin and finite non-zero direction.

Errors

Returns a GeometryError when the origin is non-finite or the direction is invalid.

pub const fn origin(self) -> Point2

Returns the ray origin.

pub const fn direction(self) -> Vector<2>

Returns the ray direction.

pub fn point_at(self, t: f64) -> Point2

Returns the point at parameter t along the ray.

Trait Implementations

impl Clone for Ray2

fn clone(&self) -> Ray2

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Ray2

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

Formats the value using the given formatter.

impl PartialEq for Ray2

fn eq(&self, other: &Ray2) -> 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.
