Struct Param 

pub struct Param<F, D> { /* private fields */ }

👎Deprecated: See curve_sampling::Fun instead

Options for sampling the image of functions ℝ → ℝ². See Sampling::param.

Implementations

impl<F, Y, D> Param<F, D>

where F: FnMut(f64) -> Y, Y: Img<D>,

pub fn n(self, n: usize) -> Self

Set the maximum number of evaluations of the function to build the sampling. Panic if n < 2.

pub fn viewport(self, vp: BoundingBox) -> Self

Set the zone of interest for the sampling. Segments that end up outside this box will not be refined.

pub fn init<'a, I>(self, ts: I) -> Self

where I: IntoIterator<Item = &'a f64>,

Add initial values of t such that f(t) (see [Sampling :: param]) must be included into the sampling in addition to the n evaluations. Only the values between a and b are taken into account (other values are ignored).

pub fn init_pt<I>(self, pts: I) -> Self

where I: IntoIterator<Item = (f64, Y)>,

Add initial points (t, f(t)) to include into the sampling in addition to the n evaluations. This allows you to use previous evaluations of f. Only the couples with first coordinate t between a and b (see [Sampling :: param]) are considered (other values are ignored).

impl<F, Y, D> Param<F, D>

where F: FnMut(f64) -> Y, Y: Img<D>,

pub fn build(self) -> Sampling<D>

Return the sampling.
