// this doesn't make _much_ difference really, since this is our only Rust source file
// but it seems it's probably better than not having it
// what we really want is to tell Rust to only regenerate the header file if the Rust code actually compiles
// but we don't have that flexibility
// and it's an issue because cbindgen tries to be fault-tolerant in some ways that don't even seem to make sense
//
// e.g. mis-spell "Option" as "Option" and you get
// void print_optional(Optio<const int8_t*> x);
// instead of
// void print_optional(const int8_t *x);
// and that's only an issue because in HLS TH dependent-file watching gives up after an error
// i.e. once the containing splice has thrown an exception once, the containing file needs a manual edit to kick it
// and that's really not helped by Rust Analyzer mostly only showing diagnostics on save
// P.S. strings to stdout?! what a terrible API
// don't get me started in the discoverability of actually then using the terminal for debugging:
// println!("cargo::warning={:?}", env::var("OUT_DIR"));
println!("cargo::rerun-if-changed=lib.rs");
