Send UTF-16 on TCP or TLS Socket

See more Socket/SSL/TLS Examples

Demonstrates how to send a string on a connected TCP or SSL/TLS socket such that it is the utf-16 byte representation that is sent. Rust

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

let socket = chilkat::Socket::new();

let tls = false;
let max_wait_ms = 20000;
let domain_or_ip_addr = "example.com".to_string();
let port = 1234;

// Connect to the whatever is expecting our connection...
if socket.connect(&domain_or_ip_addr, port, tls, max_wait_ms).is_err() {
    println!("{}", socket.last_error_text());
    return;
}

// Let's say we have an XML file saved in the utf-16 byte representation,
// and we want to send it over the connection using the utf-16 byte representation...

// First the file into a Chilkat StringBuilder.
// Tell the LoadFile method that we are reading utf-16 bytes..
let sb_xml = chilkat::StringBuilder::new();
if sb_xml.load_file("qa_data/xml/myUtf16.xml", "utf-16").is_err() {
    println!("Failed to load utf-16 XML file..");
    return;
}

// Tell the socket object that we wish to send the utf-16 byte representation of the string.
socket.set_string_charset("utf-16");

// Send the string as utf-16 bytes.
if socket.send_sb(&sb_xml).is_err() {
    println!("{}", socket.last_error_text());
    return;
}

// Let's say we wanted to instead send the string as utf-8 bytes.
// Just tell the socket object...
socket.set_string_charset("utf-8");

// Send the string as utf-8 bytes.
if socket.send_sb(&sb_xml).is_err() {
    println!("{}", socket.last_error_text());
    return;
}

// If our XML file was utf-8, then just tell the StringBuilder that we're reading utf-8.
// Once the text is properly contained in the StringBuilder, we can send the contents in any other charset (windows-1252, utf-16, utf-8, etc.) 
// as long as it make sense (i.e. we obviously can't send Japanese text using a single-byte charset such as Windows-1252).
if sb_xml.load_file("qa_data/xml/myUtf8.xml", "utf-8").is_err() {
    println!("Failed to load utf-8 XML file..");
    return;
}

// Send as utf-16
socket.set_string_charset("utf-16");

// Send the string as utf-16 bytes.
if socket.send_sb(&sb_xml).is_err() {
    println!("{}", socket.last_error_text());
    return;
}
