Struct polar_core::terms::Operation

pub struct Operation {
    pub operator: Operator,
    pub args: TermList,
}

Fields

operator: Operator

args: TermList

Implementations

impl Operation

pub fn variables(&self) -> Vec<Symbol>

Construct & return a set of symbols that occur in this operation.

pub fn ground(&self, var: Symbol, value: Term) -> Option<Self>

Replace var with a ground (non-variable) value. Checks for consistent unifications along the way: if everything’s fine, returns Some(grounded_term), but if an inconsistent ground (anti-)unification is detected, return None.

pub fn merge_constraints(&mut self, other: Self)

Augment our constraints with those on other.

Invariant: self and other are ANDs

pub fn invert(&self) -> Operation

pub fn constraints(&self) -> Vec<Operation>

pub fn add_constraint(&mut self, o: Operation)

pub fn into_term(self) -> Term

pub fn clone_with_constraints(&self, constraints: Vec<Operation>) -> Self

pub fn clone_with_new_constraint(&self, constraint: Term) -> Self

pub fn mirror(&self) -> Self

Trait Implementations
