How to get the contents of an email that originated as a T-Mobile SMS text.

Rust

// First, for the purpose of understanding the structure of the MIME,
// let's load the MIME into a Chilkat MIME object and examine the MIME structure.
let mime = chilkat::Mime::new();

let _ = mime.load_mime_file("qa_data/eml/TMobileTextMsg.eml").is_ok();
// Show the MIME structure in text format (as opposed to XML format).
println!("{}", mime.get_structure("text").unwrap_or_default());

// The MIME structure for our test email looks like this:
// multipart/related
//     text/html
//     text/plain
//     image/gif
//     image/gif
//     image/gif

// The HTML part is not considered a "related item" because the related items
// are defined as being related to the HTML part.  Therefore, we should always
// expect to find a text/html part under a multipart/related.  The HTML parts
// is simply the HTML body, and the other parts are the related items.
// If the text/plain part was to be considered as an alternative body,
// then a properly structured email would include a multipart/alternative structure.

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

let _ = email.load_eml("qa_data/eml/TMobileTextMsg.eml").is_ok();

// We should see 4 related items.
println!("Num Related Items = {}", email.num_related_items());
// There should be 0 attachments.  
println!("Num Attachments = {}", email.num_attachments());

// Find the indices of the text/plain related part, and the text/html related part
let mut i = 0;
let num_related_items = email.num_related_items();
let sb_content_type = chilkat::StringBuilder::new();
while i < num_related_items {
    let _ = sb_content_type.append(&email.get_related_content_type(i).unwrap_or_default());
    println!("{}: {}", i, sb_content_type.get_as_string().unwrap_or_default());
    if sb_content_type.contents_equal("text/plain", false) {
        println!("---- text/plain part:");
        println!("{}", email.get_related_string(i, "utf-8").unwrap_or_default());
    }

    sb_content_type.clear();
    i = i + 1;
}
