Receive a Bounded String from a Socket

See more Socket/SSL/TLS Examples

Demonstrates Socket.ReceiveStringMaxN, which receives and decodes text like ReceiveString but reads at most a given number of input bytes.

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 and decode text like ReceiveString, but read at most the given number of input bytes.
// The limit is measured in bytes, not Unicode characters.
let Ok(first_chunk) = socket.receive_string_max_n(64) else {
    println!("{}", socket.last_error_text());
    return;
};

println!("{}", first_chunk);
