Expand description

A parameterized curve that reports its extrema.

Required Methods§

Source

fn extrema( &self, ) -> ArrayVec<f64, kurbo::::param_curve::ParamCurveExtrema::extrema::{constant#0}>

Compute the extrema of the curve.

Only extrema within the interior of the curve count. At most four extrema can be reported, which is sufficient for cubic Béziers.

The extrema should be reported in increasing parameter order.

Provided Methods§

Source

fn extrema_ranges( &self, ) -> ArrayVec<Range<f64>, kurbo::::param_curve::ParamCurveExtrema::extrema_ranges::{constant#0}>

Return parameter ranges, each of which is monotonic within the range.

Source

fn bounding_box(&self) -> Rect

The smallest rectangle that encloses the curve in the range (0..1).

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
