Struct Ellipse2 

pub struct Ellipse2 { /* private fields */ }

An ellipse in the plane.

Implementations

impl Ellipse2

pub fn new( frame: Frame2, major_radius: f64, minor_radius: f64, tol: Tolerances, ) -> OgeomResult<Self>

An ellipse with the given radii, the major radius along frame’s x.

Errors

OgeomError::Construction if a radius is not finite and positive, or the minor exceeds the major.

pub const fn frame(&self) -> Frame2

The frame positioning this ellipse.

pub const fn centre(&self) -> Point2

The centre.

pub const fn major_radius(&self) -> f64

The major radius.

pub const fn minor_radius(&self) -> f64

The minor radius.

pub fn focal_distance(&self) -> f64

The distance from the centre to either focus.

pub fn eccentricity(&self) -> f64

The eccentricity, in [0, 1).

pub fn area(&self) -> f64

The area enclosed.

pub fn transformed(&self, t: &Transform2, tol: Tolerances) -> OgeomResult<Self>

This ellipse moved by t.

Errors

As Ellipse2::new.

Trait Implementations

impl Clone for Ellipse2

fn clone(&self) -> Ellipse2

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Ellipse2

impl Debug for Ellipse2

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

Formats the value using the given formatter.

impl PartialEq for Ellipse2

fn eq(&self, other: &Ellipse2) -> 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.
