#[async_trait]
impl Rpc for RpcExample {
    #[metrics_rpc("eth_sendRawTransaction")]
    async fn send_transaction(&self, tx: SignedTransaction) -> Result<Hash, Error> {
        Ok(tx.transaction.hash)
    }

    #[metrics_rpc("net_listening")]
    fn listening(&self) -> Result<bool, Error> {
        Ok(false)
    }
}

macro metrics_rpc only support IntCounter type in Prometheus
