Struct Dual 

pub struct Dual {
    pub v: f64,
    pub d: f64,
}

A Dual number for forward-mode automatic differentiation. Evaluates f(x) and f’(x) simultaneously.

Fields

v: f64

d: f64

Trait Implementations

impl Clone for Dual

fn clone(&self) -> Dual

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Dual

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

Formats the value using the given formatter.

impl PartialEq for Dual

fn eq(&self, other: &Dual) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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

impl Copy for Dual

impl StructuralPartialEq for Dual
