//! fixture executable to be used in signature_fallback testing
//! This binary listens to stdin for newline delimited json signature requests
//! and alternates between "success" and "error" responses.
//! It doesn't do any actual signing, it always returns an all zeroes sig.

    use std::io::BufRead;

    // alternate between good and bad responses
    let mut bad = false;

    // using blocking reading -- if you were actually implementing this
    // it'd probably be better to use tokio::io::AsyncBufReadExt::lines()
