Struct SetOperator 

pub struct SetOperator;

Set operator for set-valued maps (union)

Trait Implementations

impl Clone for SetOperator

fn clone(&self) -> SetOperator

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SetOperator

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

Formats the value using the given formatter.

impl Default for SetOperator

fn default() -> SetOperator

Returns the “default value” for a type.

impl<T> MergeOperator<HashSet<T>> for SetOperator

where T: Clone + Hash + Eq,

fn merge( &self, left: HashSet<T>, right: HashSet<T>, ) -> Result<HashSet<T>, MapletError>

Merge two values using the operator ⊕

fn identity(&self) -> HashSet<T>

Get the identity element for this operator

fn is_associative(&self) -> bool

Check if the operator is associative

fn is_commutative(&self) -> bool

Check if the operator is commutative

impl MergeOperator<i64> for SetOperator

fn merge(&self, _left: i64, right: i64) -> Result<i64, MapletError>

Merge two values using the operator ⊕

fn identity(&self) -> i64

Get the identity element for this operator

fn is_associative(&self) -> bool

Check if the operator is associative

fn is_commutative(&self) -> bool

Check if the operator is commutative

impl PartialEq for SetOperator

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