Struct ReifiedVar 

pub struct ReifiedVar(pub usize);

Reified logic variable.

Reified variables represent logic variables that remain fresh after goals have run.

Tuple Fields

0: usize

Trait Implementations

impl Clone for ReifiedVar

fn clone(&self) -> ReifiedVar

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReifiedVar

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

Formats the value using the given formatter.

impl PartialEq for ReifiedVar

fn eq(&self, other: &ReifiedVar) -> 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 Structure for ReifiedVar

fn occurs<'s>(&self, _x: &Var, _s: &Substitution<'s>) -> bool

Returns true if self contains a variable that is equivalent to x when considering substitution s.

fn unify<'s>( &self, _v: &Value, _s: Substitution<'s>, ) -> Option<Substitution<'s>>

Attempt to unify self with Value v under substitution s.

fn walk_star(self: Arc<Self>, _: &Substitution<'_>) -> Value

Recursively replace any variables contained in self with their substituted values.

fn reify_s<'s>(&self, s: Substitution<'s>) -> Substitution<'s>

Substitute all variables that remain fresh in self with reified variables.

fn as_any(&self) -> &dyn Any

Cast to Any reference.

fn eqv(&self, other: &Value) -> bool

Return true if self is equivalent to other.
