## Example

```rust

use std::ffi::CStr;

fn main() {
    unsafe {
        let lua = sys::luaL_newstate();
        sys::luaL_openlibs(lua);
        let script_data = b"return 1 + 2";
        let script_name = b"run_script\0";
        sys::luaL_loadbuffer(
            lua,
            script_data.as_ptr() as _,
            script_data.len() as _,
            script_name.as_ptr() as _,
        );
        sys::lua_pcall(lua, 0, 1, 0);
        let idx = sys::lua_gettop(lua);
        let s = sys::lua_tostring(lua, idx);
        let result = CStr::from_ptr(s).to_string_lossy().to_string();
        sys::lua_close(lua);

        println!("result: {}", result);
    }
}
