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: main.rs
    path of file: ./repos/shuttle/logger/src
    
    the code of the file until where you have to start completion: use std::time::Duration;

use clap::Parser;
use shuttle_common::{
    backends::{
        auth::{AuthPublicKey, JwtAuthenticationLayer},
        trace::setup_tracing,
    },
    extract_propagation::ExtractPropagationLayer,
    log::Backend,
};
use shuttle_logger::{args::Args, Postgres, Service};
use shuttle_proto::logger::logger_server::LoggerServer;
use tonic::transport::Server;
use tracing::trace;

#[tokio::ma
    
async fn main() {
    let args = Args::parse();

    setup_tracing(tracing_subscriber::registry(), Backend::Logger);

    trace!(args = ?args, "parsed args");

    let mut server_builder = Server::builder()
        .http2_keepalive_interval(Some(Duration::from_secs(60)))
        .layer(JwtAuthenticationLayer::new(AuthPublicKey::new(
            args.auth_uri,
        )))
        .layer(ExtractPropagationLayer);

    let postgres = Postgres::new(&args.db_connection_uri).await;

    let router = server_builder.add_service(LoggerServer::new(Service::new(
        postgres.get_sender(),
        postgres,
    )));

    router.serve(args.address).await.unwrap();
}
