Trait for function nodes in GP trees

Required Methods

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

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
