This module has no docstring.
A subclass of Queue that retrieves most recently added entries first.
empty(self) Return True if the queue is empty, False otherwise.
full(self)
Return True if there are maxsize items in the queue.
Note: if the Queue was initialized with maxsize=0 (the default),
then full() is never True.
get(self)
Remove and return an item from the queue.
If queue is empty, wait until an item is available.
get_nowait(self)
Remove and return an item from the queue.
Return an item if one is immediately available, else raise QueueEmpty.
join(self)
Block until all items in the queue have been gotten and processed.
The count of unfinished tasks goes up whenever an item is added to the
queue. The count goes down whenever a consumer calls task_done() to
indicate that the item was retrieved and all work on it is complete.
When the count of unfinished tasks drops to zero, join() unblocks.
put(self, item)
Put an item into the queue.
Put an item into the queue. If the queue is full, wait until a free
slot is available before adding item.
put_nowait(self, item)
Put an item into the queue without blocking.
If no free slot is immediately available, raise QueueFull.
qsize(self) Number of items in the queue.
task_done(self)
Indicate that a formerly enqueued task is complete.
Used by queue consumers. For each get() used to fetch a task,
a subsequent call to task_done() tells the queue that the processing
on the task is complete.
If a join() is currently blocking, it will resume when all items have
been processed (meaning that a task_done() call was received for every
item that had been put() into the queue).
Raises ValueError if called more times than there were items placed in
the queue.
maxsize = <property object at 0x7f0227323d10> Number of items allowed in the queue.
A subclass of Queue; retrieves entries in priority order (lowest first).
Entries are typically tuples of the form: (priority number, data).
empty(self) Return True if the queue is empty, False otherwise.
full(self)
Return True if there are maxsize items in the queue.
Note: if the Queue was initialized with maxsize=0 (the default),
then full() is never True.
get(self)
Remove and return an item from the queue.
If queue is empty, wait until an item is available.
get_nowait(self)
Remove and return an item from the queue.
Return an item if one is immediately available, else raise QueueEmpty.
join(self)
Block until all items in the queue have been gotten and processed.
The count of unfinished tasks goes up whenever an item is added to the
queue. The count goes down whenever a consumer calls task_done() to
indicate that the item was retrieved and all work on it is complete.
When the count of unfinished tasks drops to zero, join() unblocks.
put(self, item)
Put an item into the queue.
Put an item into the queue. If the queue is full, wait until a free
slot is available before adding item.
put_nowait(self, item)
Put an item into the queue without blocking.
If no free slot is immediately available, raise QueueFull.
qsize(self) Number of items in the queue.
task_done(self)
Indicate that a formerly enqueued task is complete.
Used by queue consumers. For each get() used to fetch a task,
a subsequent call to task_done() tells the queue that the processing
on the task is complete.
If a join() is currently blocking, it will resume when all items have
been processed (meaning that a task_done() call was received for every
item that had been put() into the queue).
Raises ValueError if called more times than there were items placed in
the queue.
maxsize = <property object at 0x7f0227323d10> Number of items allowed in the queue.
A queue, useful for coordinating producer and consumer coroutines.
If maxsize is less than or equal to zero, the queue size is infinite. If it
is an integer greater than 0, then "await put()" will block when the
queue reaches maxsize, until an item is removed by get().
Unlike the standard library Queue, you can reliably know this Queue's size
with qsize(), since your single-threaded asyncio application won't be
interrupted between calling qsize() and doing an operation on the Queue.
empty(self) Return True if the queue is empty, False otherwise.
full(self)
Return True if there are maxsize items in the queue.
Note: if the Queue was initialized with maxsize=0 (the default),
then full() is never True.
get(self)
Remove and return an item from the queue.
If queue is empty, wait until an item is available.
get_nowait(self)
Remove and return an item from the queue.
Return an item if one is immediately available, else raise QueueEmpty.
join(self)
Block until all items in the queue have been gotten and processed.
The count of unfinished tasks goes up whenever an item is added to the
queue. The count goes down whenever a consumer calls task_done() to
indicate that the item was retrieved and all work on it is complete.
When the count of unfinished tasks drops to zero, join() unblocks.
put(self, item)
Put an item into the queue.
Put an item into the queue. If the queue is full, wait until a free
slot is available before adding item.
put_nowait(self, item)
Put an item into the queue without blocking.
If no free slot is immediately available, raise QueueFull.
qsize(self) Number of items in the queue.
task_done(self)
Indicate that a formerly enqueued task is complete.
Used by queue consumers. For each get() used to fetch a task,
a subsequent call to task_done() tells the queue that the processing
on the task is complete.
If a join() is currently blocking, it will resume when all items have
been processed (meaning that a task_done() call was received for every
item that had been put() into the queue).
Raises ValueError if called more times than there were items placed in
the queue.
maxsize = <property object at 0x7f0227323d10> Number of items allowed in the queue.
Raised when Queue.get_nowait() is called on an empty Queue.

Exception.with_traceback(tb) --
set self.__traceback__ to tb and return self.
args = <attribute 'args' of 'BaseException' objects>
Raised when the Queue.put_nowait() method is called on a full Queue.

Exception.with_traceback(tb) --
set self.__traceback__ to tb and return self.
args = <attribute 'args' of 'BaseException' objects>
