What is the problem?

Normally the Rust standard library code sets SIGPIPE to SIG_IGN before your fn main() runs. This makes you see an error if you pipe your output to something like head:

fn main() {
    loop {
        println!("hello world");
    }
}

$ ./main | head
hello world
thread 'main' panicked at 'failed printing to stdout: Broken pipe (os error 32)', library/std/src/io/stdio.rs:1016:9
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrac

How do I solve it?

Add the following to your Cargo.toml to keep SIGPIPE as SIG_DFL so your program is nicely killed instead of panicking:

[dependencies]
sigpipe-untouched = "0.1.0"

$ ./main | head
hello world
