Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl ContainsVariables for WhereClause

fn accumulate_mentioned_variables(&self, acc: &mut BTreeSet<Variable>)

fn collect_mentioned_variables(&self) -> BTreeSet<Variable>

impl Debug for WhereClause

impl Eq for WhereClause

impl PartialEq for WhereClause

fn eq(&self, other: &WhereClause) -> 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.
