sysexits-rs (sysexits) is a library that provides the system exit code constants as defined by <sysexits.h>.

This library implements the Termination trait, so this can be returned from the main function.

Add this to your Cargo.toml:

[dependencies]
sysexits = "0.7.5"

fn main() -> sysexits::ExitCode {
    let bytes = [0xf0, 0x9f, 0x92, 0x96];
    match std::str::from_utf8(&bytes) {
        Ok(string) => {
            println!("{string}");
            sysexits::ExitCode::Ok
        }
        Err(err) => {
            eprintln!("{err}");
            sysexits::ExitCode::DataErr
        }
    }
}
