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: file_list_deleted.rs
    path of file: ./repos/openobserve/src/service/compact
    
    the code of the file until where you have to start completion: // Copyright 2023 Zinc Labs Inc.

// it
    
async fn process_file(file: &str) -> Result<Vec<String>, anyhow::Error> {
    // download file list from storage
    let data = match storage::get(file).await {
        Ok(data) => data,
        Err(_) => {
            return Ok(Vec::new());
        }
    };

    // uncompress file
    let uncompress = zstd::decode_all(data.reader())?;
    let uncompress_reader = BufReader::new(uncompress.reader());
    // parse file list
    let mut records = Vec::with_capacity(16);
    for line in uncompress_reader.lines() {
        let line = line?;
        if line.is_empty() {
            continue;
        }
        records.push(line);
    }

    Ok(records)
}
