Trait Curve 

pub trait Curve: Debug + Downcast {
    // Required methods
    fn get_point(&self, u: Float) -> Point3;
    fn project(&self, point: Point3) -> Float;
}

Parametric curve

Required Methods

fn get_point(&self, u: Float) -> Point3

Get a point on the curve with parameter u

fn project(&self, point: Point3) -> Float

Get parameter of nearest point on the curve to the given point

Implementations

impl dyn Curve

pub fn is<__T: Curve>(&self) -> bool

Returns true if the trait object wraps an object of type __T.

pub fn downcast<__T: Curve>(self: Box<Self>) -> Result<Box<__T>, Box<Self>>

Returns a boxed object from a boxed trait object if the underlying object is of type __T. Returns the original boxed trait if it isn’t.

pub fn downcast_rc<__T: Curve>(self: Rc<Self>) -> Result<Rc<__T>, Rc<Self>>

Returns an Rc-ed object from an Rc-ed trait object if the underlying object is of type __T. Returns the original Rc-ed trait if it isn’t.

pub fn downcast_ref<__T: Curve>(&self) -> Option<&__T>

Returns a reference to the object within the trait object if it is of type __T, or None if it isn’t.

pub fn downcast_mut<__T: Curve>(&mut self) -> Option<&mut __T>

Returns a mutable reference to the object within the trait object if it is of type __T, or None if it isn’t.
