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".
