Unable to blocklist

[ccleve]

I'm attempting to create a minimal bindings.rs. I have a C header file that has many transitive includes, and I'd like to omit them all. I only want bindings that I have explicitly included.

In 0.61.0, this code worked fine:

    let bindings = bindgen::Builder::default()
        .header("src/cfuncs/myheader.h")
        .blocklist_type("*") // block everything not explicitly added
        .allowlist_function("rdb_.*")
        .allowlist_var("RDB_.*")
        .allowlist_type("rdb_.*")
        .parse_callbacks(Box::new(bindgen::CargoCallbacks))
        .generate()
        .expect("Unable to generate bindings");

I upgraded to 0.64.0 and it ignored my blocklist. It started pulling in all of the transitive dependencies.

I added a few lines:

    let bindings = bindgen::Builder::default()
        .header("src/cfuncs/myheader.h")
        .blocklist_type("*") // block everything not explicitly added

        // these lines added
        .blocklist_file("*")
        .blocklist_function("*")
        .blocklist_item("*")
        .opaque_type("*")

        .allowlist_function("rdb_.*")
        .allowlist_var("RDB_.*")
        .allowlist_type("rdb_.*")
        .parse_callbacks(Box::new(bindgen::CargoCallbacks))
        .generate()
        .expect("Unable to generate bindings");

but this command still pulls in all of the transitives.

How do I get it to behave like 0.61.0?
