Struct LineHit

pub struct LineHit { /* private fields */ }

A point where a line meets a circle, held exactly.

Implementations

impl LineHit

pub const fn line(self) -> Line

The line this hit lies on.

pub const fn circle(self) -> Circle

The circle this hit lies on.

pub const fn branch(self) -> Branch

Which solution of the quadratic this is.

pub fn cmp_param(self, value: f64) -> Result<Sign, ExactError>

Sign of t - value: whether this hit comes before (Negative), at, or after the line parameter value. With 0.0 and 1.0 this answers “is the hit inside the segment from..to”.

pub fn orientation(self, a: Point2, b: Point2) -> Result<Sign, ExactError>

Which side of the directed line a -> b this hit lies on.

pub fn approx_param(self) -> f64

The parameter rounded to f64, for output only.

Never use this to make a decision; ask a sign question instead.

pub fn approx_point(self) -> Point2

The point rounded to f64, for output only.

Trait Implementations

impl Clone for LineHit

fn clone(&self) -> LineHit

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LineHit

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

Formats the value using the given formatter.

impl PartialEq for LineHit

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