Macro new_tokio_smtp::smtp_chain

macro_rules! smtp_chain {
    ($con:ident with $oer:expr => [$($cmd:expr),*]) => { ... };
}

creates a chain of commands and them to the given connection

This will call boxed() on every command, while puting them into a vector which is then passed to cain.

Example

use futures::future::{self, Future};
use new_tokio_smtp::chain::OnError;
use new_tokio_smtp::{command, Connection, ReversePath, ForwardPath};


let fut = future
    ::lazy(|| mock_create_connection())
    .and_then(|con| smtp_chain!(con with OnError::StopAndReset => [
        command::Mail::new(
            ReversePath::from_unchecked("test@sender.test")),
        command::Recipient::new(
            ForwardPath::from_unchecked("test@receiver.test")),
        command::Data::from_buf(concat!(
            "Date: Thu, 14 Jun 2018 11:22:18 +0000\r\n",
            "From: Sendu <test@sender.test>\r\n",
            "\r\n",
            "...\r\n"
        ))
    ]))
    .and_then(|(con, smtp_chain_result)| {
        if let Err((at_idx, err)) = smtp_chain_result {
            println!("server says no on the cmd with index {}: {}", at_idx, err)
        }
        con.quit()
    });

// ... this are tokio using operation make sure there is
//     a running tokio instance/runtime/event loop
