Struct thrussh::client::Connection

pub struct Connection<R: AsyncRead + AsyncWrite, H: Handler> { /* private fields */ }

Client connection. A connection implements Future, returning () when it finishes (for instance if the client and server agree to close the connection).

Implementations

impl<R: AsyncRead + AsyncWrite, H: Handler> Connection<R, H>

pub fn channel_close(&mut self, channel: ChannelId)

Ask the server to close a channel, finishing any pending write and read.

pub fn handler(&self) -> &H

Gets a borrow to the connection’s handler.

pub fn handler_mut(&mut self) -> &mut H

Gets a mutable borrow to the connection’s handler.

pub fn is_channel_open(&self, channel: ChannelId) -> bool

pub fn channel_open_session(&mut self) -> Result<ChannelId, Error>

Request a session channel (the most basic type of channel). This function returns Some(..) immediately if the connection is authenticated, but the channel only becomes usable when it’s confirmed by the server, as indicated by the confirmed field of the corresponding Channel.

pub fn channel_open_x11(
    &mut self,
    originator_address: &str,
    originator_port: u32
) -> Result<ChannelId, Error>

Request an X11 channel, on which the X11 protocol may be tunneled.

    originator_address: &str,
    originator_port: u32
) -> Result<ChannelId, Error>

Open a TCP/IP forwarding channel. This is usually done when a connection comes to a locally forwarded TCP/IP port. See RFC4254. The TCP/IP packets can then be tunneled through the channel using .data().

pub fn set_env(
    &mut self,
    channel: ChannelId,
    want_reply: bool,
    variable_name: &str,
    variable_value: &str
)

pub fn request_shell(&mut self, want_reply: bool, channel: ChannelId)

Request a remote shell.

pub fn exec(&mut self, channel: ChannelId, want_reply: bool, command: &str)

    &mut self,
    channel: ChannelId,
    col_width: u32,

    pix_width: u32,
    pix_height: u32
)

Inform the server that our window size has changed.

pub fn tcpip_forward(&mut self, want_reply: bool, address: &str, port: u32)

Request the forwarding of a remote port to the client. The server will then open forwarding channels (which cause the client to call .channel_open_forwarded_tcpip()).

pub fn cancel_tcpip_forward(&mut self, want_reply: bool, address: &str, port: u32)

Cancel a previous forwarding request.

pub fn data(
    &mut self,
    channel: ChannelId,
    extended: Option<u32>,
    data: &[u8]
) -> usize

Send data to a channel. The number of bytes added to the “sending pipeline” (to be processed by the event loop) is returned.
