amqp-rs 0.1.0.post1

Python AMQP Client Library developed in Rust using PyO3.

amqp-rs

amqp-rs is a Python client library with a high level of abstraction for manipulating messages in RabbitMQ.

What is "amqprs"

It is a Python extension developed in Rust using PyO3. It acts as a wrapper for the amqp-client-python library, inheriting its performance, stability, and asynchronous capabilities.

Features

• Thread Safe: Built on Rust's memory safety guarantees.
• Asynchronous API: Powered by tokio and pyo3-asyncio for high-performance I/O.
• Automatic Management: Handles the creation and management of queues, exchanges, and channels automatically.
• Persistence: Built-in connection persistence and automatic reconnection.
• Flexible Exchanges: Full support for direct, topic, and fanout exchange types.
• RPC Support: Native abstractions for Remote Procedure Calls (RPC).
• Compression: Built-in support for zstd, zlib, and lz4 encoding.
• TLS/SSL: Robust encryption support including mutual TLS (client authentication).
• Graceful Shutdown: Ability to stop consumers cleanly and process remaining messages before closing.

Installation

You can install amqp-rs directly from PyPI using uv or pip:

uv add amqp-rs

Configuration

The library uses specialized objects to manage connection behavior and Quality of Service (QoS):

Connection Settings

• ConfigOptions: Defines primary queue names and RPC exchange/queue settings.

• Config: Contains connection parameters such as host, port, username, password, and virtual_host.

QoS and Confirmations (QoSConfig)

You can fine-tune performance and reliability using QoSConfig:

• Confirmations: Enable or disable publisher confirmations for standard publishing or RPC (pub_confirm, rpc_client_confirm, rpc_server_confirm).

• Acknowledge: Set automatic acknowledgement for subscriptions or RPC handlers (sub_auto_ack, rpc_server_auto_ack).

• Prefetch: Control the flow by setting prefetch counts for different connection types to manage how many unacknowledged messages the client can hold.
