Send Email with a vCard

Demonstrates how to create a simple email, attach a vcard, and send it. Rust

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// The mailman object is used for sending and receiving email.
let mailman = chilkat::MailMan::new();

// Set the SMTP server.
mailman.set_smtp_host("smtp.chilkatsoft.com");

// Set the SMTP login/password (if required)
mailman.set_smtp_username("myUsername");
mailman.set_smtp_password("myPassword");

// Create a new email object
let email = chilkat::Email::new();

email.set_subject("This is a vcard test");
email.set_body("This is a vcard test");
email.set_from("Chilkat Admin <admin@chilkatsoft.com>");
let _ = email.add_to("Chilkat Support", "support@chilkatsoft.com").is_ok();
// To add more recipients, call AddTo, AddCC, or AddBcc once per recipient.

// A vCard is an email attachment having a Content-Type = "text/x-vcard".
// Call AddStringAttachment to add a vcard from an in-memory string.
// The filename should have a ".vcf" file extension.  Chilkat will automatically
// recognize it and set the content-type to "text/x-vcard";

// Your application is responsible for providing the vcard formatted string.  For example:
// See http://en.wikipedia.org/wiki/VCard
// 
// begin:vcard
// fn:Matt Smith
// n:Smith;Matt
// org:Chilkat Software, Inc.
// tel;work:630-784-9670
// url:http://www.chilkatsoft.com
// version:2.1
// end:vcard

let vcard = "begin:vcard ...".to_string();
if email.add_string_attachment("admin.vcf", &vcard).is_err() {
    println!("{}", email.last_error_text());
    return;
}

// Call SendEmail to connect to the SMTP server and send.
// The connection (i.e. session) to the SMTP server remains
// open so that subsequent SendEmail calls may use the
// same connection.  
if mailman.send_email(&email).is_err() {
    println!("{}", mailman.last_error_text());
    return;
}

// Some SMTP servers do not actually send the email until 
// the connection is closed.  In these cases, it is necessary to
// call CloseSmtpConnection for the mail to be  sent.  
// Most SMTP servers send the email immediately, and it is 
// not required to close the connection.  We'll close it here
// for the example:
if mailman.close_smtp_connection().is_err() {
    println!("Connection to SMTP server not closed cleanly.");
}

println!("Mail with vCard Sent!");
