While the idea/content could be salvaged, this book is in dire need of proof-reading and checking that their examples are valid. Building a wasm sandbox, you need to be able to compile C/C++ into wasm code. The #[wasm_bindgen] directive (if that is what they are called in Rust!) indicates that this function is exposed by the module, in this case it is a solve function that takes a sudoku grid as a string, then returns the solution (also as a string). Web-Assembly Friendly. 39K stars @ag_dubs/hello-wasm. c -o addTwo. Putting Rust and Wasm together.
