You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: partial_udf.rs
    path of file: ./repos/Daft/src/daft-dsl/src/functions/python
    
    the code of the file until where you have to start completion: use std::hash::{Hash, Hasher};

use pyo3::{
   
    
    fn hash<H: Hasher>(&self, state: &mut H) {
        let py_obj_hash = Python::with_gil(|py| self.0.as_ref(py).hash());
        match py_obj_hash {
            // If Python object is hashable, hash the Python-side hash.
            Ok(py_obj_hash) => py_obj_hash.hash(state),
            // Fall back to hashing the pickled Python object.
            Err(_) => serde_json::to_vec(self).unwrap().hash(state),
        }
    }
