How to insert or update an XMP array property (bag, seq, or alt). Rust

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

// Sample JPG's with XMP metadata may be found at:
// http://www.chilkatsoft.com/testData/xmp/sample1.jpg

// http://www.chilkatsoft.com/testData/xmp/sample3.jpg

println!("Num embedded XMP docs: {}", xmp.num_embedded());

// Assuming there is at least one, get the 1st.
// (There is typically never more than one, but theoretically it's possible.)
if let Ok(xml) = xmp.get_embedded(0) {

    // Create an object to hold one or more string values.
    let sa = chilkat::StringArray::new();
