Persistent set implementation. Built on top of the persistent map. The set supports all operations in the Set protocol and is Hashable. Do not instantiate directly, instead use the factory functions :py:func:`s` or :py:func:`pset` to create an instance. Random access and insert is log32(n) where n is the size of the set. Some examples: >>> s = pset([1, 2, 3, 1]) >>> s2 = s.add(4) >>> s3 = s2.remove(2) >>> s pset([1, 2, 3]) >>> s2 pset([1, 2, 3, 4]) >>> s3 pset([1, 3, 4]) )�_map� __weakref__c s t t| ��| �}||_|S )N)�superr �__new__r )�cls�m�self)� __class__� �C/opt/alt/python37/lib64/python3.7/site-packages/pyrsistent/_pset.pyr s z PSet.__new__c C s || j kS )N)r )r �elementr r r � __contains__% s zPSet.__contains__c C s t | j�S )N)�iterr )r r r r �__iter__( s z PSet.__iter__c C s t | j�S )N)�lenr )r r r r �__len__+ s z PSet.__len__c C s2 t s| sdtt| �� S d�tt| ��dd� �S )N�pz pset([{0}])r ���)�PY2�str�set�format)r r r r �__repr__. s z PSet.__repr__c C s | � � S )N)r )r r r r �__str__4 s z PSet.__str__c C s t | j�S )N)�hashr )r r r r �__hash__7 s z PSet.__hash__c C s t t| �ffS )N)�pset�list)r r r r � __reduce__: s zPSet.__reduce__� c C s t ttdd� |D ��|d��S )Nc s s | ]}|d fV qdS )TNr )�.0�kr r r � <genexpr>@ s z&PSet._from_iterable.<locals>.<genexpr>)�pre_size)r r �dict)r �itr) r r r �_from_iterable> s zPSet._from_iterablec C s | � � �|��� S )z~ Return a new PSet with element added >>> s1 = s(1, 2) >>> s1.add(3) pset([1, 2, 3]) )�evolver�add� persistent)r r r r r r.

Create a new evolver for this pset. For a discussion on evolvers in general see the documentation for the pvector evolver. Create the evolver and perform various mutating updates to it: >>> s1 = s(1, 2, 3) >>> e = s1.evolver() >>> _ = e.add(4) >>> len(e) 4 >>> _ = e.remove(1) The underlying pset remains the same: >>> s1 pset([1, 2, 3]) The changes are kept in the evolver. An updated pmap can be created using the persistent() function on the evolver. >>> s2 = e.persistent() >>> s2 pset([2, 3, 4]) The new pset will share data with the original pset in the same way that would have been done if only using operations on the pset. )r r> )r r r r r- � s z PSet.evolver)r% )*r: r; r< �__doc__r= r r r r r r r! r$ � classmethodr, r. r2 r3 r5 �objectr> r? r- r �__le__�__lt__�__gt__�__ge__�__eq__�__ne__�__and__�__or__�__sub__�__xor__�issubset� issuperset�union� intersection� difference�symmetric_difference� isdisjoint� __classcell__r r )r r r sH #r r r% c C s | st S tj| |d�S )z� Creates a persistent set from iterable.
