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: summary.rs
    path of file: ./repos/Toshi/toshi-server/src/handlers
    
    the code of the file until where you have to start completion: use hyper::{Response, StatusCode};
use log::{debug, info};
use serde::Serialize;
use std::time::Instant;

use toshi_types::*;

use crate::handlers::ResponseFuture;
use crate::utils::{empty_with_code, with_body};
use std::sync::Ar
    
pub async fn flush<C: Catalog>(catalog: Arc<C>, index: &str) -> ResponseFuture {
    if let Ok(local_index) = catalog.get_index(index) {
        let writer = local_index.get_writer();
        let mut write = writer.lock().await;
        let opstamp = write.commit().unwrap();
        info!("Successful commit: {}", index);
        Ok(with_body(FlushResponse { opstamp }))
    } else {
        debug!("Could not find index: {}", index);
        Ok(empty_with_code(StatusCode::NOT_FOUND))
    }
}
