我正在尝试将 *.cc 链接到 Rust。

构建.rs：

fn main() {
    cc::Build::new()
        .file("src/bindings.cc")
        .cargo_metadata(true)
        .cpp(true)
        .compile("bindings");
}

绑定.cc：

extern "C" {
    leveldb::Status db_get(
        LevelDB* db,
        const char* key, size_t keylen,
        const char** val, size_t* vallen,
        bool fillCache
    ) {
        printf("0: %p, 1: %p, 2: %d, 3: %p, 4: %p, 5: %s\n",
            db,
            key, keylen,
            val, vallen,
            fillCache ? "true" : "false"
        );
        leveldb::Status status;
        return status;
    }
}

系统.rs:

enum LevelDB {}

// why? leveldb::Status has private property const char*
// It doesnt …
