HH\ImmSet::keys

Returns an ImmVector containing the values of this ImmSet

public function keys(): ImmVector<arraykey>;

ImmSets don't have keys, so this will return the values.

This method is interchangeable with toImmVector() and values().

Returns

• ImmVector<arraykey> - an ImmVector containing the values of the current ImmSet.
