Module tcp_client

Send/receive data to/from a TCP server and associated types.

Usage

let hostname = "github.com";
// let ip_address: IpAddress = [140, 82, 114, 3]; // github.com

let port: Port = 80;
let mode: TransportMode = TransportMode::Tcp;
if let Err(e) = TcpClient::build(&mut wifi).connect(
    hostname,
    port,
    mode,
    &mut delay,
    &mut |tcp_client| {
        defmt::info!(
            "TCP connection to {:?}:{:?} successful",
            hostname,
            port
        );
        defmt::info!("Hostname: {:?}", tcp_client.server_hostname());
        defmt::info!("Sending HTTP Document: {:?}", http_document.as_str());
        match tcp_client.send_data(&http_document) {
            Ok(response) => {
                defmt::info!("Response: {:?}", response)
            }
            Err(e) => {
                defmt::error!("Response error: {:?}", e)
            }
        }
    },
) {
    defmt::error!(
        "TCP connection to {:?}:{:?} failed: {:?}",
        hostname,
        port,
        e
    );
}

Structs

TcpClient

A client type that connects to and performs send/receive operations with a remote server using the TCP protocol.

Traits

Connect

Allows for a TcpClient instance to connect to a remote server by providing either a Hostname or an IpAddress. This trait also makes it possible to implement and support IPv6 addresses.
