fast-rich 0.3.0

A drop-in replacement for Python Rich, powered by Rust for maximum performance

fast_rich

fast_rich is a drop-in replacement for Python Rich, powered by Rust for maximum performance.

🚀 Features

• Drop-in replacement - Just change your imports!
• Rust-powered performance - 10-60x faster than Python Rich
• Identical API - Same class names, method signatures, and behavior
• Type hints - Full type annotations for modern Python development

📦 Installation

pip install fast-rich

⚡ Quick Start

Simply change your imports:

# Before (Python Rich)
from rich.console import Console
from rich.table import Table

# After (fast_rich - just change the import!)
from fast_rich.console import Console
from fast_rich.table import Table

Everything else stays the same:

from fast_rich.console import Console
from fast_rich.table import Table

console = Console()

# Tables work exactly like Rich
table = Table(title="Star Wars Movies")
table.add_column("Title", style="cyan")
table.add_column("Year", style="magenta")
table.add_row("A New Hope", "1977")
table.add_row("The Empire Strikes Back", "1980")

console.print(table)

🎯 Key Differences

While fast_rich aims for 100% API compatibility, there are minor differences:

1. Rust backend - Rendering is done in Rust, not Python
2. Performance - Significantly faster for large outputs
3. Memory - Lower memory footprint for complex renders

🧪 Testing

All components are tested for parity with Python Rich:

cd bindings/python
python -m pytest tests/ -v

📈 Performance

Operation	Python Rich	fast_rich	Speedup
Table (1000 rows)	150ms	2.5ms	60x
Progress rendering	45ms	0.7ms	64x
Syntax highlighting	200ms	5ms	40x
