Trait piet_common::kurbo::ParamCurve
pub trait ParamCurve: Sized {
fn eval(&self, t: f64) -> Point;

fn start(&self) -> Point { ... }

}Expand description
A curve parametrized by a scalar.
If the result is interpreted as a point, this represents a curve. But the result can be interpreted as a vector as well.
Required Methods
fn eval(&self, t: f64) -> Point
fn eval(&self, t: f64) -> Point
Evaluate the curve at parameter t.
Generally t is in the range [0..1].
fn subsegment(&self, range: Range<f64>) -> Self
fn subsegment(&self, range: Range<f64>) -> Self
Get a subsegment of the curve for the given parameter range.
Provided Methods
fn subdivide(&self) -> (Self, Self)
fn subdivide(&self) -> (Self, Self)
Subdivide into (roughly) halves.
