Xuanwo opened a new issue, #1767:
URL: https://github.com/apache/incubator-opendal/issues/1767

   To implement a layer in python or nodejs, we should build a `PythonLayer` to `NodejsLayer` first.
   
   Let's take Python as an example. First, we will implement `Layer` for `PythonLayer` and then call the native function inside it. Bindings can provide their own layer interface based on their specific needs. For instance, a Python binding can expose a layer class that includes functions such as `pre_stat`, `post_stat`, `pre_read`, and `post_read`.
   
   So the code will be like:
   
   ```rust
   impl Layer for PythonLayer {
       async fn stat(&self, path: &str, op: OpStat) -> Result<Metadata> {
           call_python(pre_stat(path, &op))
           self.inner.stat()
           call_python(post_stat(path, &op))
       }
   }
   ```
