Struct stroke::line::LineSegment

pub struct LineSegment<P> { /* private fields */ }

LineSegment defined by a start and an endpoint, evaluatable anywhere inbetween using interpolation parameter t: [0,1] in eval() A LineSegment is equal to a linear Bezier curve, which is why there is no specialized type for that case.

Implementations

impl<P> LineSegment<P>where P: Point,

pub fn new(start: P, end: P) -> Self

pub fn eval(&self, t: P::Scalar) -> P

pub fn split(&self, t: P::Scalar) -> (Self, Self)

pub fn distance_to_point(&self, p: P) -> P::Scalar

Return the distance from the LineSegment to Point p by calculating the projection

pub fn axis(&self, t: P::Scalar, axis: usize) -> P::Scalar

Sample the coordinate axis of the segment at t (expecting t between 0 and 1).

pub fn derivative(&self) -> P

Return the derivative function. The derivative is also a bezier curve but of degree n-1 - In the case of a line the derivative vector.

pub fn bounding_box(&self) -> [(P::Scalar, P::Scalar); P::DIM]

Return the bounding box of the line as an array of (min, max) tuples for each dimension (its index)

Trait Implementations

impl<P: Clone> Clone for LineSegment<P>

fn clone(&self) -> LineSegment<P>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<P: Debug> Debug for LineSegment<P>

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

Formats the value using the given formatter.

impl<P> From<LineSegment<P>> for BezierSegment<P>where P: Point,

fn from(s: LineSegment<P>) -> Self

Converts to this type from the input type.

impl<P: PartialEq> PartialEq<LineSegment<P>> for LineSegment<P>

fn eq(&self, other: &LineSegment<P>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
