Displaying email content

[GreeFine]

Hello, I used a previous versions of this crate to fetch and get the email content, but with the updated version i don't find anything on how to access the contents of the fetch.

Previously i fetched and got my reponsse like this:

match imap_socket.fetch(&seq, "BODY.PEEK[HEADER.FIELDS (FROM SUBJECT DATE)]") {
    Ok(lines) => {
        println!("{:?}", lines[0]);
        // from = lines[1];
        // subject = lines[2];
        // date = lines[3];
    }
    Err(e) => println!("Error Fetching email {}: {}", x, e),
};

But now even with this and the example you give, I only get a list of flags and some ID/UID
Fetch { message: 348, flags: ["\\Seen"], uid: None, rfc822_header: None, rfc822: None }Mailbox emails number = 538

I have looked in the documentation and found that now fetch return a vector of imap::Fetch, but i am not abble to find anything leading to my fetch content.

Also, i am very new to RUST so i don't really understand all i am doing 😕

Hi there! Yes, the old version of this crate did not parse the response that comes back from the server, and instead had you parse it out yourself. As of #58, that has changed, but it does mean that there are some attributes that we don't expose just because we haven't though of them :) The BODY field specifically is parsed as of #76 (through Fetch::body()), but due to #69, I can't actually publish a new version with that at the moment, so you'll have to add the crate as a git dependency.

Alternatively, you can request RFC822 (instead of BODY.PEEK and such), and then access that through Fetch::rfc822. You can see how I do that in buzz here.

Thank you for the support @jonhoo !
Here is the solution i use with your answer.
Maybe put something alike in the example section might help people like me in the future.

let domain = "imap.gmail.com";
let port = 993;
let socket_addr = (domain, port);
let ssl_connector = TlsConnector::builder().unwrap().build().unwrap(); //Using native-tls = "0.1"
let mut imap_socket = Client::secure_connect(socket_addr, domain, &ssl_connector).unwrap();

imap_socket
    .login("[email protected]", "password")
    .unwrap();

match imap_socket.select("INBOX") {
     Ok(mailbox) => {
         println!("{}", mailbox);
     }
     Err(e) => println!("Error selecting INBOX: {}", e),
};

match imap_socket.fetch("2", "RFC822") {
    Ok(messages) => {
        for message in messages.iter() {
            let lines: Vec<&str> = str::from_utf8(message.rfc822().unwrap())
                .unwrap()
                .split("\n")
                .collect();
            for i in 0..lines.len() {
                println!("Lines[{}] {}", i, lines[i]);
            }
        }
    }
    Err(e) => println!("Error Fetching email 2: {}", e),
};

imap_socket.logout().unwrap();
