Struct terms::Term

pub struct Term<F> { /* fields omitted */ }

A term.

Subterms are reference counter using [std::rc::Arc].

Methods

impl<F> Term<F>

pub fn new(f: F, subs: Vec<Self>) -> Self where
    F: Clone, 

pub fn from_slice(f: F, subs: &[Self]) -> Self where
    F: Clone, 

pub fn symbol(&self) -> &F

pub fn sub_terms(&self) -> &Vec<Self>

pub fn depth(&self) -> u64

pub fn random(alphabet: &[F], max_depth: u64) -> Term<F> where
    F: Clone + Ranked, 

Generate a random term with the given alphabet. The alphabet must contain at least one constant (of arity 0), otherwise it will panic.
