Struct protocol_ftp_client::FtpReceiver

pub struct FtpReceiver {
    // some fields omitted
}

"Passive" side of FTP protocol, which mean that receiver expects some data from remote server. As soon as it recieves enought data it can "advance" to transmitter state, i.e. fill buffer with commands to be furhter send to the remote server

Methods

impl FtpReceiver

fn new() -> Self

fn try_advance(self, buffer: &[u8]) -> Result<FtpTransmitter, Self>

Try to consume Reciver by parsing buffer and andvacne into Transmitter. In the case of error, it returns unmodified Reciver as the error. The actually happen error can be obtatied via take_error

In case of success it remembers the last successfull state, probably switches it and returns Transmitter object

fn take_error(&mut self) -> Option<FtpError>

Returns tha last occurred error, and internally sets up None

fn to_transmitter(self) -> FtpTransmitter

Sometimes you need manually advance to Transmitter e.g. in case of Authorization Error, you can re-send other credentials
