This release is a pre-release and may not be stable for production use.
pymizu
Single-producer single-consumer channels for Python: a bounded ring buffer with optional timeouts on receives and sentinel return values for full, timeout, and closed states. The transport is in-process.
Installation
pip install pymizu
Usage
import pymizu
ch = pymizu.inproc_channel(2)
ch.send("a")
ch.send(42)
ch.send("b") # full: returns the pymizu.FULL sentinel
ch.recv()
# 'a'
ch.recv()
# 42
ch.recv(timeout=0) # empty: do not wait
# <pymizu.TIMEOUT>
ch.close()
timeout is in seconds on a monotonic clock: None (the default) and
math.inf wait indefinitely, and 0 polls. The buffer is
lock-guarded, so a producer thread and a consumer thread may exchange
values without an external lock.
Terminal states surface as sentinel singletons, not exceptions:
pymizu.FULL, pymizu.TIMEOUT, and pymizu.CLOSED.
pymizu.is_sentinel(x) is an identity test for use where payloads are
untrusted.
