Enum ExtrapolationPolicy 

pub enum ExtrapolationPolicy {
    Boundary,
    Exception,
    Fill(f64),
    Periodic,
}

Extrapolation policy controlling behavior when a query point falls outside the domain of argvals.

Used with fdata_interpolate_with_policy to give callers explicit control over out-of-range query handling instead of the silent boundary clamp that fdata_interpolate applies.

Variants

Boundary

Clamp the query point to the nearest boundary value.

A query at t < t_min returns the interpolated value at t_min; a query at t > t_max returns the interpolated value at t_max.

Exception

Return an error for any out-of-range query point.

Returns Err(FdarError::InvalidParameter { parameter: "new_argvals", .. }) when a query point lies outside [argvals[0], argvals[m-1]].

Fill(f64)

Fill out-of-range cells with a constant value.

Periodic

Wrap query points modulo the domain length (periodic extension).

A query at t_min - delta returns the same value as t_max - delta. Uses the guarded-modulo recipe ((t - t_min) % L + L) % L to handle negative remainders for t < t_min.
