This blog post details how the author created native Go bindings for Apache OpenDAL-a Rust-based unified data access layer-without relying on CGo, by combining the purego library and libffi. The solution enables Go programs to call Rust (via C) functions directly, overcoming previous integration hurdles, simplifying cross-compilation, reducing binary sizes, and achieving better performance compared to traditional CGo-based bindings.
