Receive Text up to a Matching Sequence

See more Socket/SSL/TLS Examples

Demonstrates Socket.ReceiveUntilMatch, which receives bytes until an exact byte sequence is found. The match string is encoded using StringCharset and compared byte-for-byte.

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

// Connect to the server using TLS.  The 3rd argument enables the TLS handshake after the TCP
// connection succeeds; the 4th is the maximum time to wait, in milliseconds.
let b_tls = true;
let max_wait_ms = 5000;
if socket.connect("example.com", 5000, b_tls, max_wait_ms).is_err() {
    println!("{}", socket.last_error_text());
    return;
}

// StringCharset controls the character encoding used when sending and receiving text.
socket.set_string_charset("utf-8");
// Send a request using a simple application-defined text protocol in which each message ends with a
// CRLF.
let command = "STATUS\r\n".to_string();
if socket.send_string(&command).is_err() {
    println!("{}", socket.last_error_text());
    return;
}

// Receive bytes until an exact byte sequence is found.  The match string is encoded using
// StringCharset and compared byte-for-byte.  Here the server marks the end of its response with an
// application-defined marker.
let Ok(response) = socket.receive_until_match("<EOM>") else {
    println!("{}", socket.last_error_text());
    return;
};

println!("{}", response);
