Trait Implementations

impl Clone for ArithmeticFunction

fn clone(&self) -> ArithmeticFunction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ArithmeticFunction

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ArithmeticFunction

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Function for ArithmeticFunction

fn arity(&self) -> usize

Get the arity (number of arguments) of this function

fn random<R: Rng>(rng: &mut R) -> Self

Generate a random function

fn functions() -> &'static [Self]

Get the set of available functions

fn apply(&self, args: &[f64]) -> f64

Apply this function to the given arguments

fn to_string(&self) -> String

Convert to string representation

impl PartialEq for ArithmeticFunction

fn eq(&self, other: &ArithmeticFunction) -> 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 Serialize for ArithmeticFunction

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
