Enum ClientMode 

pub enum ClientMode {
    Passive,
    ExtendedPassive,
    Active,
}

A FTP client can run in two main modes: active and passive.

The passive mode is the simpler to run, you simply ask the server for a host to connect and connect to it, this is your data connection (for more information about the FTP protocol, check RFC959).

The active mode is different, you must open a port on your machine and use that to connect to the server. This can be a problem if you have firewalls set on your machine/network, for the common user, the passive mode should work fine.

The ExtendedPassive mode listed is simply the passive mode with support for IPV6.

Variants
