Rust Requires Chilkat v11.0.0+

Example: Email.GetDsnInfo method

See more Email Object Examples

Demonstrates how to call the GetDsnInfo method. Rust

let email = chilkat::Email::new();

if email.load_eml("qa_data/eml/sample_multipart_report.eml").is_err() {
    println!("{}", email.last_error_text());
    return;
}

let json = chilkat::JsonObject::new();
if email.get_dsn_info(&json).is_err() {
    println!("{}", email.last_error_text());
    return;
}

json.set_emit_compact(false);
println!("{}", json.emit().unwrap_or_default());

// Sample output:

// {
//   "reporting-mta": "dns; Exchange2016.example.com",
//   "final-recipient": [
//     "herb.butterworth1247692846@gmail.com"
//   ],
//   "action": "failed",
//   "status": "5.1.1",
//   "remote-mta": "dns; mx.google.com",
//   "x-supplementary-info": "<mx.google.com #5.1.1 smtp;550-5.1.1 The email account that you tried to reach does not exist.

//   "x-display-name": "herb.butterworth1247692846@gmail.com"

// Code for parsing the JSON:
