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: sst-convert.rs
    path of file: ./repos/incubator-horaedb/src/tools/src/bin
    
    the code of the file until where you have to start completion: // Licensed to the Apache Software Foundation (ASF) under one
// or more contribu
    
fn main() {
    let args = Args::parse();
    let rt = Arc::new(new_runtime(4));
    let rt2 = rt.clone();
    rt.block_on(async move {
        if let Err(e) = run(args, rt2).await {
            eprintln!("Convert failed, err:{e}");
        }
    });
}
