Enum IRTerm

pub enum IRTerm {
    Constant(String),
    UserVariable(String),
    Array(Vec<IRTerm>),
    AuxiliaryVariable(u32),
    RenamedVariable(u32, Box<IRTerm>),
    AnonymousVariable(u32),
}

Variants

Constant(String)

UserVariable(String)

Array(Vec<IRTerm>)

AuxiliaryVariable(u32)

Primarily used to establish f-string constraints.

RenamedVariable(u32, Box<IRTerm>)

AnonymousVariable(u32)

It should be safe to assume that a given AnonymousVariable(i) will not appear again in the AST.

Implementations

impl IRTerm

pub fn is_constant(&self) -> bool

Returns true if the IRTerm is Constant.

pub fn is_constant_or_compound_constant(&self) -> bool

pub fn is_underlying_anonymous_variable(&self) -> bool

Returns true if the IRTerm is AnonymousVariable or it was renamed from an AnonymousVariable.

pub fn as_constant(&self) -> Option<&str>

pub fn get_original(&self) -> &IRTerm

Gets the original IRTerm from a renamed one, or returns itself.

pub fn is_anonymous_variable(&self) -> bool

Returns true if the irterm is AnonymousVariable.

impl IRTerm

pub fn variables(&self, include_anonymous: bool) -> HashSet<IRTerm>

Trait Implementations

impl Auxiliary for IRTerm

fn aux(anonymous: bool) -> IRTerm

impl Clone for IRTerm

fn clone(&self) -> IRTerm

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IRTerm

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

Formats the value using the given formatter.

impl Display for IRTerm

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

Formats the value using the given formatter.

impl From<ModusTerm> for IRTerm

fn from(modus_term: ModusTerm) -> Self

Converts to this type from the input type.

impl Ground for IRTerm

fn is_ground(&self) -> bool

impl Hash for IRTerm

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 Ord for IRTerm

fn cmp(&self, other: &IRTerm) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for IRTerm

fn eq(&self, other: &IRTerm) -> 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 PartialOrd for IRTerm

fn partial_cmp(&self, other: &IRTerm) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
