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: dna_bundle.rs
    path of file: ./repos/holochain/crates/holochain_types/src/dna
    
    the code of the file until where you have to start completion: use std::{
    collections::{BTreeMap, HashMap},
    path::{Path, PathBuf},
};

use crate::prelude::*;
use futures::StreamExt;
use holo_hash::*;
use mr_bundle::{Location, ResourceBytes};

#[cfg(test)]
mod test;

/// A bundle of Wasm zomes, respresented as a file.
#
    
    pub async fn into_dna_file(self, modifiers: DnaModifiersOpt) -> DnaResult<(DnaFile, DnaHash)> {
        let (integrity, coordinator, wasms) = self.inner_maps().await?;
        let (dna_def, original_hash) = self.to_dna_def(integrity, coordinator, modifiers)?;

        Ok((
            DnaFile::new(dna_def.content, wasms.into_iter().map(|(_, v)| v)).await,
            original_hash,
        ))
    }
