logcast

A simple helper that sends logs over UDP, for programs without terminal output, such as TUIs.

Example

Usage

cargo add logcast

I recommend creating a macro. Specify the address and port where the client will listen for logs. To view the logs, open another terminal and run a program that listens for UDP messages without exiting, such as ncat -ul --keep-open 8080, as shown in the example below.

use logcast::send_log;

macro_rules! log {
    ($msg:expr) => {
        if let Err(e) = send_log($msg, "127.0.0.1:8080") {
            eprintln!("Error: {}", e);   
        }
    };
}

log!("Test");
log!(&format!("{:?}", service));

Output:

└─$ ncat -ul --keep-open 8080 
[2025-11-10 20:55:04] Test
[2025-11-10 20:55:04] Service { name: "cron.service", description: "Regular background program processing daemon", state: ServiceState { load: "loaded", active: "active", sub: "running", file: "enabled" } }
