It consists of two main steps:
1. Generating Bindings with `bindgen`:
- The `build.rs` script uses `bindgen` to generate Rust FFI (Foreign
Function Interface) bindings for the AMD SMI C library. This step
automatically exports all enums, structs, unions, and unsafe functions
from the C library into Rust. This provides a comprehensive low-level
interface to the AMD SMI library.
2. Implementing Safe Rust Wrappers:
- The generated bindings are then wrapped in safe Rust functions. These
safe wrappers handle error checking, resource management, and provide a
more idiomatic Rust interface. This ensures that users of the library
can interact with the AMD SMI functions without dealing with unsafe code
directly.
