Enum DifferenceMode 

pub enum DifferenceMode {
    Forward,
    Backward,
    Central,
}

Mode of finite difference approximation.

Variants

Forward

f’(x) ~ (f(x+h) - f(x)) / h

Backward

f’(x) ~ (f(x) - f(x-h)) / h

Central

f’(x) ~ (f(x+h) - f(x-h)) / (2h) – O(h^2) accuracy

Trait Implementations

impl Clone for DifferenceMode

fn clone(&self) -> DifferenceMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DifferenceMode

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

Formats the value using the given formatter.

impl PartialEq for DifferenceMode

fn eq(&self, other: &DifferenceMode) -> 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.
