HH\Vector::toImmSet
Returns an immutable set (ImmSet) based on the values of the current
Vector
public function toImmSet(): ImmSet<Tv>;
Returns
ImmSet<Tv>- AnImmSetcontaining the unique values of the currentVector.
Examples
This example shows that converting a Vector to an ImmSet also removes duplicate values:
// This Vector contains repetitions of 'red' and 'blue'
$v = Vector {'red', 'green', 'red', 'blue', 'red', 'yellow', 'blue'};
$imm_set = $v->toImmSet();
\var_dump($imm_set is \HH\ImmSet<_>);
\var_dump($imm_set);
