Struct Circle 

pub struct Circle { /* private fields */ }

A circle in space.

Implementations

impl Circle

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

A circle of radius in the xy plane of frame.

Errors

OgeomError::Construction if radius is not finite and positive.

pub fn through( a: Point, b: Point, c: Point, tol: Tolerances, ) -> OgeomResult<Self>

The circle through three points.

Errors

OgeomError::Construction if the points are collinear or any two coincide; no circle passes through them.

pub const fn frame(&self) -> Frame

The frame positioning this circle.

pub const fn centre(&self) -> Point

The centre.

pub const fn radius(&self) -> f64

The radius.

pub fn length(&self) -> f64

The circumference.

pub fn area(&self) -> f64

The area enclosed.

pub fn distance_to(&self, p: Point) -> f64

The shortest distance from p to the circle.

Zero on the circle, and positive both inside and outside; this is the distance to the curve, not to the disc it bounds.

pub fn contains(&self, p: Point, tol: Tolerances) -> bool

Whether p lies on the circle within tol.confusion().

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

This circle moved by t.

Errors

OgeomError::Construction if the transformed frame is degenerate.

Trait Implementations

impl Clone for Circle

fn clone(&self) -> Circle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Circle

impl Debug for Circle

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

Formats the value using the given formatter.

impl PartialEq for Circle

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