Struct Parabola 

pub struct Parabola { /* private fields */ }

A parabola in space, opening along its frame’s x axis.

Implementations

impl Parabola

pub fn new(frame: Frame, focal: f64, tol: Tolerances) -> OgeomResult<Self>

A parabola with the given focal length in the xy plane of frame.

The apex is at the frame origin and the curve opens along +x; the focus sits at distance focal from the apex along +x.

Errors

OgeomError::Construction if focal is not finite and positive. A zero focal length degenerates to a ray.

pub const fn frame(&self) -> Frame

The frame positioning this parabola.

pub const fn apex(&self) -> Point

The apex.

pub const fn focal(&self) -> f64

The focal length: apex to focus.

pub fn focus(&self) -> Point

The focus.

pub const fn eccentricity(&self) -> f64

The eccentricity, which is 1 for every parabola.

pub fn transformed(&self, t: &Transform, tol: Tolerances) -> OgeomResult<Self>

This parabola moved by t.

Errors

OgeomError::Construction if the transformed frame is degenerate.

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 Copy for Parabola

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.
