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) c ttS)N)rrY/var/www/html/Resume-Scraper/venv/lib/python3.12/site-packages/trio/testing/_sequencer.pyzSequencer.:s E*rF)factoryinitzdefaultdict[int, Event]_sequence_pointszset[int]_claimed)defaultrbool_brokencxK||jvrtd||jr td|jj||dk7r= |j|j d{|jr td d|j|dzjy7B#t j$rCd|_|jjD]}|jtddwxYw#|j|dzjwxYww)Nz"Attempted to reuse sequence point zsequence broken!rTz+Sequencer wait cancelled -- sequence broken) r RuntimeErrorraddrwaitr Cancelledvaluesset)selfpositionevents r__call__zSequencer.__call__@s! t}} $!CH:NO O <<12 2 (# q= ;++H5::<<<<<&'9:: 6   ! !(Q, / 3 3 5=?? # !2299; EIIK "A    ! !(Q, / 3 3 5sIAD: B<7B:8B<<D:D!D::B<r9sU"#* ""- e$F6F6% F6r
