Struct ConicLineHit

pub struct ConicLineHit { /* private fields */ }

One exact hit of a line with a conic: t = (-beta +- sqrt(disc)) / alpha on the line, or t = -gamma / (2 beta) in the linear case.

Implementations

impl ConicLineHit

pub const fn line(&self) -> Line

The line this hit lies on.

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

Exact sign of t - value.

pub fn compare_along(&self, other: &Self) -> Result<Sign, ExactError>

Exact sign of self - other along their common line.

pub fn approx_point(&self) -> Point2

An approximate point, for output only.

Trait Implementations

impl Clone for ConicLineHit

fn clone(&self) -> ConicLineHit

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ConicLineHit

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

Formats the value using the given formatter.

impl PartialEq for ConicLineHit

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