Append Part to MIME

See more MIME Examples

Demonstrates the AppendPart method for adding sub-parts to MIME. Rust

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

// Create a text/plain part.
let pt_mime = chilkat::Mime::new();
let _ = pt_mime.set_body_from_plain_text("This is the plain text body");
println!("{}", pt_mime.get_mime().unwrap_or_default());
println!("****");

// The ptMime contains:
// ---------------------------------------
// 	Content-Type: text/plain
// 	Content-Transfer-Encoding: 7bit
// 
// 	This is the plain text body
// ---------------------------------------

// Start with an empty MIME object...
let top_level_mime = chilkat::Mime::new();

// Initialize it to a multipart Content-Type.  We'll use multipart/mixed.
let _ = top_level_mime.new_multipart_mixed();

// Append the ptMime as a child.
let _ = top_level_mime.append_part(&pt_mime);
println!("{}", top_level_mime.get_mime().unwrap_or_default());
println!("****");

// The topLevelMime contains:
// --------------------------
// 	Content-Type: multipart/mixed; boundary="------------010907090104040508040404"
// 
// 	--------------010907090104040508040404
// 	Content-Type: text/plain
// 	Content-Transfer-Encoding: 7bit
// 
// 	This is the plain text body
// 	--------------010907090104040508040404--
// 

// IMPORTANT: A copy of the MIME passed in AppendPart is appended.
// Therefore, in this case, changing ptMime does not change the text/plain sub-part in topLevelMime.
// For example:
pt_mime.set_body("this is the new plain text body.");
// topLevelMime is unchanged.
println!("{}", top_level_mime.get_mime().unwrap_or_default());
println!("****");

// To change the content in topLevelMime, we must get the text/plain part.
// For example:

let pt_mime2 = chilkat::Mime::new();
let _ = top_level_mime.part_at(0, &pt_mime2);

pt_mime2.set_body("this is the new plain text body.");
// Now topLevelMime is changed.
println!("{}", top_level_mime.get_mime().unwrap_or_default());
