Struct ContinuationCurve

pub struct ContinuationCurve<T, C, D> { /* private fields */ }

The curve that results from chaining two curves.

Additionally the transition of the samples is guaranteed to not make sudden jumps. This is useful if you really just know about the shapes of your curves and don’t want to deal with stitching them together properly when it would just introduce useless complexity. It is realized by translating the second curve so that its start sample point coincides with the first curves’ end sample point.

Curves of this type are produced by Curve::chain_continue.

Domain

The first curve’s domain must be right-finite and the second’s must be left-finite to get a valid ContinuationCurve.

Trait Implementations

impl<T: Clone, C: Clone, D: Clone> Clone for ContinuationCurve<T, C, D>

fn clone(&self) -> ContinuationCurve<T, C, D>

Returns a copy of the value.

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

impl<T, C, D> Curve<T> for ContinuationCurve<T, C, D>

where T: VectorSpace, C: Curve<T>, D: Curve<T>,

fn domain(&self) -> Interval

The interval over which this curve is parametrized.

fn sample_unchecked(&self, t: f32) -> T

Sample a point on this curve at the parameter value t, extracting the associated value. This is the unchecked version of sampling, which should only be used if the sample time t is already known to lie within the curve’s domain.

fn sample(&self, t: f32) -> Option<T>

Sample a point on this curve at the parameter value t, returning None if the point is outside of the curve’s domain.

fn sample_clamped(&self, t: f32) -> T

Sample a point on this curve at the parameter value t, clamping t to lie inside the domain of the curve.

fn sample_iter( &self, iter: impl IntoIterator<Item = f32>, ) -> impl Iterator<Item = Option<T>>

where Self: Sized,

Sample a collection of n >= 0 points on this curve at the parameter values t_n, returning None if the point is outside of the curve’s domain.

fn sample_iter_unchecked( &self, iter: impl IntoIterator<Item = f32>, ) -> impl Iterator<Item = T>

where Self: Sized,

Sample a collection of n >= 0 points on this curve at the parameter values t_n, extracting the associated values. This is the unchecked version of sampling, which should only be used if the sample times t_n are already known to lie within the curve’s domain.

fn sample_iter_clamped( &self, iter: impl IntoIterator<Item = f32>, ) -> impl Iterator<Item = T>

where Self: Sized,

fn map<S, F>(self, f: F) -> MapCurve<T, S, Self, F>

where Self: Sized, F: Fn(T) -> S,

Create a new curve by mapping the values of this curve via a function f; i.e., if the sample at time t for this curve is x, the value at time t on the new curve will be f(x).

fn reparametrize<F>(self, domain: Interval, f: F) -> ReparamCurve<T, Self, F>

where Self: Sized, F: Fn(f32) -> f32,

Create a new Curve whose parameter space is related to the parameter space of this curve by f. For each time t, the sample from the new curve at time t is the sample from this curve at time f(t). The given domain will be the domain of the new curve. The function f is expected to take domain into self.domain().

fn reparametrize_linear( self, domain: Interval, ) -> Result<LinearReparamCurve<T, Self>, LinearReparamError>

where Self: Sized,

Linearly reparametrize this Curve, producing a new curve whose domain is the given domain instead of the current one. This operation is only valid for curves with bounded domains; if either this curve’s domain or the given domain is unbounded, an error is returned.

fn reparametrize_by_curve<C>(self, other: C) -> CurveReparamCurve<T, Self, C>

where Self: Sized, C: Curve<f32>,

Reparametrize this Curve by sampling from another curve.

where Self: Sized, C: Curve<S> + Sized,

fn chain<C>(self, other: C) -> Result<ChainCurve<T, Self, C>, ChainError>

where Self: Sized, C: Curve<T>,

Create a new Curve by composing this curve end-to-start with another, producing another curve with outputs of the same type. The domain of the other curve is translated so that its start coincides with where this curve ends.

fn reverse(self) -> Result<ReverseCurve<T, Self>, ReverseError>

where Self: Sized,

Create a new Curve inverting this curve on the x-axis, producing another curve with outputs of the same type, effectively playing backwards starting at self.domain().end() and transitioning over to self.domain().start(). The domain of the new curve is still the same.

fn repeat(self, count: usize) -> Result<RepeatCurve<T, Self>, RepeatError>

where Self: Sized,

Create a new Curve repeating this curve N times, producing another curve with outputs of the same type. The domain of the new curve will be bigger by a factor of n + 1.

fn forever(self) -> Result<ForeverCurve<T, Self>, RepeatError>

where Self: Sized,

Create a new Curve repeating this curve forever, producing another curve with outputs of the same type. The domain of the new curve will be unbounded.

fn ping_pong(self) -> Result<PingPongCurve<T, Self>, PingPongError>

where Self: Sized,

Create a new Curve chaining the original curve with its inverse, producing another curve with outputs of the same type. The domain of the new curve will be twice as long. The transition point is guaranteed to not make any jumps.

fn chain_continue<C>( self, other: C, ) -> Result<ContinuationCurve<T, Self, C>, ChainError>

where Self: Sized, T: VectorSpace, C: Curve<T>,

Create a new Curve by composing this curve end-to-start with another, producing another curve with outputs of the same type. The domain of the other curve is translated so that its start coincides with where this curve ends.

fn resample<I>( &self, segments: usize, interpolation: I, ) -> Result<SampleCurve<T, I>, ResamplingError>

where Self: Sized, I: Fn(&T, &T, f32) -> T,

Resample this Curve to produce a new one that is defined by interpolation over equally spaced sample values, using the provided interpolation to interpolate between adjacent samples. The curve is interpolated on segments segments between samples. For example, if segments is 1, only the start and end points of the curve are used as samples; if segments is 2, a sample at the midpoint is taken as well, and so on. If segments is zero, or if this curve has an unbounded domain, then a ResamplingError is returned.

fn samples( &self, samples: usize, ) -> Result<impl Iterator<Item = T>, ResamplingError>

where Self: Sized,

Extract an iterator over evenly-spaced samples from this curve. If samples is less than 2 or if this curve has unbounded domain, then an error is returned instead.

fn resample_uneven<I>( &self, sample_times: impl IntoIterator<Item = f32>, interpolation: I, ) -> Result<UnevenSampleCurve<T, I>, ResamplingError>

where Self: Sized, I: Fn(&T, &T, f32) -> T,

Resample this Curve to produce a new one that is defined by interpolation over samples taken at a given set of times. The given interpolation is used to interpolate adjacent samples, and the sample_times are expected to contain at least two valid times within the curve’s domain interval.

fn by_ref(&self) -> &Self

where Self: Sized,

Borrow this curve rather than taking ownership of it. This is essentially an alias for a prefix &; the point is that intermediate operations can be performed while retaining access to the original curve.

fn flip<U, V>(self) -> impl Curve<(V, U)>

where Self: Sized + Curve<(U, V)>,

Flip this curve so that its tuple output is arranged the other way.
