HH\Vector::toSet

Returns a Set based on the values of the current Vector

public function toSet(): Set<Tv>;

Returns

• Set<Tv> - A Set containing the unique values of the current Vector.

Examples

This example shows that converting a Vector to a Set also removes duplicate values:

// This Vector contains repetitions of 'red' and 'blue'
$v = Vector {'red', 'green', 'red', 'blue', 'red', 'yellow', 'blue'};

$set = $v->toSet();

\var_dump($set is \HH\Set<_>);
\var_dump($set);
