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: mod.rs
    path of file: ./repos/meilisearch/milli/src/documents
    
    the code of the file until where you have to start completion: mod builder;
mod enriched;
mod primary_key;
mod reader;
mod serde_impl;

use std::fmt::Debug;
use std::io;
use std::str::Utf8Error;

use bimap::BiHashMap;
pub use builder::DocumentsBatchBuilder;
pub use enrich
    
    pub fn recreate_json(&self, document: &obkv::KvReaderU16) -> Result<Object> {
        let mut map = Object::new();

        for (k, v) in document.iter() {
            // TODO: TAMO: update the error type
            let key =
                self.0.get_by_left(&k).ok_or(crate::error::InternalError::DatabaseClosing)?.clone();
            let value = serde_json::from_slice::<serde_json::Value>(v)
                .map_err(crate::error::InternalError::SerdeJson)?;
            map.insert(key, value);
        }

        Ok(map)
    }
