Lo3: High-Performance Python Logging with Rust (Alpha Version)
Overview
Lo3 is an extremely fast, Rust-based logging solution for Python applications. It provides a simple Python interface while leveraging Rust's performance to deliver logging capabilities up to 80 times faster than Python's native logging module in high-volume scenarios.
Please Note: This is an alpha version with limited features. Currently, RustPyLogger only supports logging to files. Additional features are in active development.
Current Features

High-performance logging to files (up to 80x faster than Python's native logging)
Python-friendly API with familiar log levels (debug, info, warning, error)
Thread-safe operations
Efficient handling of high-volume logs
Support for additional context (kwargs) in log messages
Minimal CPU and memory overhead

Planned Features (In Development)

Support for all handlers provided in logging
Structured logging support
Asynchronous logging
Log rotation and archiving
Configurable log formatting

Installation

via pypi:
pip install lo3

Usage
Here's a simple example of how to use Lo3 in its current alpha state:
from lo3 import RustLogger

# Initialize the logger (currently only supports file logging)
logger = RustLogger("app.log")

# Log messages at different levels
logger.debug("This is a debug message", {"extra": "info"})
logger.info("This is an info message")
logger.warning("This is a warning")
logger.error("This is an error", {"error_code": 500})

# Ensure all logs are written
logger.flush()

Performance
In our benchmarks, Lo3 showed significant performance improvements over Python's native logging module:

Test: Writing 1,000,000 log messages (250,000 each of debug, info, warning, and error) to a file
Lo3: ~101.39 seconds
Python's logging module: ~522.20 seconds

This represents an 80x speedup in this high-volume logging scenario.
Benchmarking
