sto-ns vs ffcharge vs rotamer

A lightweight, pure Rust, no-std kernel for exact ns Slater-type orbital Coulomb integrals, optimized for both semi-empirical and ab initio methods.

A lightweight pure Rust library for fast, residue-based force field charge assignment (AMBER/CHARMM) in molecular modeling pipelines.

A Rust library for NERF-based sidechain coordinate placement for 29 amino acid types; build.rs bakes all bond geometry as f32 literals, custom libm-free sincosf/rsqrtf, #[repr(C)] stack-only output, zero heap, no-std.
