Instances of this class implement a ``__call__`` method which returns an async context manager. The idea is that you pass a sequence number to ``__call__`` to say where this block of code should go in the linear sequence. Block 0 starts immediately, and then block N doesn't start until block N-1 has finished. Example: An extremely elaborate way to print the numbers 0-5, in order:: async def worker1(seq): async with seq(0): print(0) async with seq(4): print(4) async def worker2(seq): async with seq(2): print(2) async with seq(5): print(5) async def worker3(seq): async with seq(1): print(1) async with seq(3): print(3) async def main(): seq = trio.testing.Sequencer() async with trio.open_nursery() as nursery: nursery.start_soon(worker1, seq) nursery.start_soon(worker2, seq) nursery.start_soon(worker3, seq) cCsttS)N)rrrrW/home/air/sanwanet/gpt-api/venv/lib/python3.10/site-packages/trio/testing/_sequencer.py:szSequencer.F)factoryinitzdefaultdict[int, Event]_sequence_pointszset[int]_claimed)defaultrbool_brokenpositionintreturnAsyncIterator[None]c Cs||jvr td||jrtd|j||dkrNz |j|IdHWntjyFd|_|jD]}| q:tddw|jrNtdzdVW|j|d dS|j|d w)Nz"Attempted to reuse sequence point zsequence broken!rTz+Sequencer wait cancelled -- sequence broken) r RuntimeErrorraddrwaitr Cancelledvaluesset)selfreventrrr__call__@s0   *zSequencer.__call__N)rrrr) __name__ __module__ __qualname____doc__attrsfieldr__annotations__r"rrrr%rrrrr s 'r ) __future__r collectionsr contextlibrtypingrr*rrr collections.abcr finaldefiner rrrrs
