rust-sasa-python

A high-performance Python library for computing SASA (Solvent Accessible Surface Area) using Rust as the backend. This library provides a clean, Pythonic interface to the fast RustSASA calculation engine.

Features

• 🦀 Powered by RustSASA: Leverages Rust's performance and safety.
• ⚡️ Ludicrous Speed: 63X faster than Biopython, 5X faster than Freesasa.
• 🐍 Pythonic Interface: Clean, intuitive API.
• 🔧 Configurable: Customizable probe radius and sampling points.
• 📁 PDB and mmCIF SUPPORT: Supports both PDB and mmCIF files.

Installation

pip install rust-sasa-python

Quick Start

import rust_sasa_python as sasa

# Simple calculation - use convenience function
result = sasa.calculate_protein_sasa("protein.pdb")
print(f"Total SASA: {result.total:.2f}")

# Builder pattern for more control
calculator = (sasa.SASACalculator("protein.pdb")
              .with_probe_radius(1.2)
              .with_n_points(2000))
result = calculator.calculate_protein()
print(f"Total SASA: {result.total:.2f}")
print(f"Polar SASA: {result.polar:.2f}")
print(f"Non-polar SASA: {result.non_polar:.2f}")
