Witnesscalc Adapter

This project provides a Rust adapter for compiling and linking Circom circuit witness generator C++ sources into a native library for target platforms (e.g., mobile devices). It includes macros and functions to facilitate the integration of witness generation into Rust codebases.

Usage

In build.rs, add the following code to compile the witness generator C++ sources into a native library and link to it:

witnesscalc_adapter::build_and_link("../path to directory containing your C++ sources");

In your main code, use the witness macro to generate a witness for a given input:

witnesscalc_adapter::witness!(<circuit name>);
