Cloudtoid Interprocess for Python

API guide · Queue concepts · Website

Fast shared-memory byte queues. Exchange messages directly with Rust, C, Go, Node.js, and .NET processes using the same v3 queue.

Install

Requires Python 3.9 or later.

python -m pip install cloudtoid-interprocess

Example

from cloudtoid_interprocess import Publisher, Subscriber

with Subscriber("example", 65536) as subscriber, Publisher("example", 65536) as publisher:
    if publisher.try_send(b"hello"):
        print(subscriber.receive(timeout=1.0))

Build from source

In an activated virtual environment, run maturin develop --release from this directory.

Queues are transient: once all publishers and subscribers are gone, unread messages are lost. Keep at least one endpoint connected throughout a handoff between processes. See the API guide for waiting, errors, ownership, and limits.
