Struct Parabola 

pub struct Parabola { /* private fields */ }

A parabola descriptor using a vertex and focal parameter.

Implementations

impl Parabola

pub fn new(vertex: Point2, focal_parameter: f64) -> Option<Self>

Creates a parabola with a finite, non-zero focal parameter.

pub const fn kind(self) -> ConicKind

Returns the conic kind.

pub const fn vertex(self) -> Point2

Returns the vertex.

pub const fn focal_parameter(self) -> f64

Returns the focal parameter.

Trait Implementations

impl Clone for Parabola

fn clone(&self) -> Parabola

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Parabola

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

Formats the value using the given formatter.

impl PartialEq for Parabola

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