Trait libtelnet_rs::TelnetEvents

pub trait TelnetEvents {
    fn on_iac(&self, command: u8) { ... }
    fn on_negotiation(&self, command: u8, option: u8) { ... }
    fn on_subnegotiation(&self, option: u8, size: usize, buffer: Vec<u8>) { ... }
    fn on_data(&self, size: usize, buffer: Vec<u8>) { ... }

A trait for event handlers of Telnet events.

Example

struct TelEvent;

impl TelnetEvents for TelEvent {
  fn on_iac(&self, command: u8) {
    println!("IAC: {}", command);
  }
  fn on_data(&self, size: usize, buffer: Vec<u8>) {
    println!(
      "Data: {} byte(s) | {}",
      size,
      String::from_utf8(buffer).unwrap()
    );
  }
  fn on_send(&self, size: usize, buffer: Vec<u8>) {
    println!("Send: {} byte(s) | {:?}", size, buffer);
  }
  fn on_negotiation(&self, command: u8, option: u8) {
    println!("Negotiate: {} {}", command, option);
  }
  fn on_subnegotiation(&self, option: u8, size: usize, buffer: Vec<u8>) {
    match String::from_utf8(buffer.clone()) {
      Ok(text) => {
        println!("Subnegotiation: {} - {} byte(s) | {}", option, size, text);
      }
      Err(_) => {
        println!(
          "Subnegotiation: {} - {} byte(s) | {:?}",
          option, size, buffer
        );
      }
    }
  }
}
