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: ipns.rs
    path of file: ./repos/rust-ipfs/http/src/v0
    
    the code of the file until where you have to start completion: use crate::v0::support::{with_ipfs, StringError, StringSerialized};
use ipfs::{Ipfs, IpfsPath, IpfsTypes};
use serde::{Deserialize, Serialize};
use warp::{query, Filter, Rejection, Reply};

#[derive(Debug, Deserialize)]
pub struct ResolveQuery {
    // the name to resolve
    arg: StringSerialized<IpfsPath>,
    // FIXME: unsupported
    #[allow(unused)]
    #[serde(rename = "dht-record-count")]
    dht_record_count: Option<usize>,
    // FIXME: unsupported
    #[allow(unused)]
    #[serde(rename = "dht-timeout")]
    dht_timeout: Option<String>,
}

pub fn 
    
async fn dns_query<T: IpfsTypes>(ipfs: Ipfs<T>, query: DnsQuery) -> Result<impl Reply, Rejection> {
    let DnsQuery { arg, recursive } = query;
    // attempt to parse the argument prepended with "/ipns/" if it fails to parse like a compliant
    // IpfsPath and there is no leading slash
    let path = if !arg.starts_with('/') {
        if let Ok(parsed) = arg.parse() {
            Ok(parsed)
        } else {
            format!("/ipns/{}", arg).parse()
        }
    } else {
        arg.parse()
    }
    .map_err(StringError::from)?;

    let path = ipfs
        .resolve_ipns(&path, recursive.unwrap_or(false))
        .await
        .map_err(StringError::from)?
        .to_string();

    let response = DnsResponse { path };

    Ok(warp::reply::json(&response))
}
