Function interpolate_hermite 

pub fn interpolate_hermite<Field, U, T>(
    segments: &[HermiteSegment<Field, T>],
    time: &[Quantity<T>],
) -> Result<U, IntegrationError>
where
    Field: Integrable,
    U: TensorVec<Item = Field::Point>,

Finds the containing segment and evaluates it there, over a whole grid of requested times.
