 RustSASA is a Rust library for computing the absolute solvent accessible surface area (ASA/SASA) of each atom in a given protein structure using the Shrake-Rupley algorithm[1].
 ## RustSASA Implementation vs Biopython Implementation
 Benchmarks were performed on an M2 Apple Mac with 8GB of RAM and 8 Cores with the protein AF-A0A2K5XT84-F1 (AlphaFold).
