Enum Term 

pub enum Term {
    Var(String),
    Const(Constant),
    Fun(String, Vec<Term>),
    Ref(TermRef),
}

A logical term in TensorLogic

Variants

Var(String)

Variable (e.g., ?X)

Const(Constant)

Constant value

Fun(String, Vec<Term>)

Function application (e.g., f(X, Y))

Ref(TermRef)

Reference to another term via CID

Implementations

impl Term

pub fn is_var(&self) -> bool

Check if term is a variable

pub fn is_const(&self) -> bool

Check if term is a constant

pub fn is_ground(&self) -> bool

Check if term is ground (contains no variables)

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

Collect all variables in the term

pub fn complexity(&self) -> usize

Get the complexity of the term (number of nodes)

Trait Implementations

impl Clone for Term

fn clone(&self) -> Term

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Term

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Term

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Term

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

Formats the value using the given formatter.

impl Hash for Term

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Term

fn eq(&self, other: &Term) -> 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 Term

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Term

impl StructuralPartialEq for Term
