A client handler. Note that messages can be received from the server at any time during a session.
Associated Types
type Error: Debug
Error type returned by the futures.
type FutureBool: Future<Item=(Self, bool), Error=Self::Error> + FromFinished<(Self, bool), Self::Error>
A future ultimately resolving into a boolean, which can be returned by some parts of this handler.
type FutureUnit: Future<Item=Self, Error=Self::Error> + FromFinished<Self, Self::Error>
A future ultimately resolving into a boolean, which can be returned by some parts of this handler.
type SessionUnit: Future<Item=(Self, Session), Error=Self::Error> + FromFinished<(Self, Session), Self::Error>
A future ultimately resolving into unit, which can be returned by some parts of this handler.
Provided Methods
Called when the server sends us an authentication banner. This is usually meant to be shown to the user, see RFC4252 for more details.
fn check_server_key(self, server_public_key: &PublicKey) -> Self::FutureBool
Called to check the server's public key. This is a very important step to help prevent man-in-the-middle attacks. The default implementation rejects all keys.
fn channel_open_confirmation(self,
channel: ChannelId,
session: Session)
-> Self::SessionUnit
channel: ChannelId,
session: Session)
-> Self::SessionUnit
Called when the server confirmed our request to open a channel. A channel can only be written to after receiving this message (this library panics otherwise).
fn channel_close(self,
channel: ChannelId,
session: Session)
-> Self::SessionUnit
channel: ChannelId,
session: Session)
-> Self::SessionUnit
Called when the server closes a channel.
fn channel_eof(self, channel: ChannelId, session: Session) -> Self::SessionUnit
Called when the server sends EOF to a channel.
fn channel_open_failure(self,
channel: ChannelId,
reason: ChannelOpenFailure,
description: &str,
language: &str,
session: Session)
-> Self::SessionUnit
channel: ChannelId,
reason: ChannelOpenFailure,
description: &str,
language: &str,
session: Session)
-> Self::SessionUnit
Called when the server rejected our request to open a channel.
fn channel_open_forwarded_tcpip(self,
channel: ChannelId,
connected_address: &str,
connected_port: u32,
originator_address: &str,
originator_port: u32,
session: Session)
-> Self::SessionUnit
channel: ChannelId,
connected_address: &str,
connected_port: u32,
originator_address: &str,
originator_port: u32,
session: Session)
-> Self::SessionUnit
Called when a new channel is created.
fn data(self,
channel: ChannelId,
extended_code: Option<u32>,
data: &[u8],
session: Session)
-> Self::SessionUnit
channel: ChannelId,
extended_code: Option<u32>,
data: &[u8],
session: Session)
-> Self::SessionUnit
Called when the server sends us data. The extended_code
parameter is a stream identifier, None
is usually the
standard output, and Some(1)
is the standard error. See
RFC4254.
fn xon_xoff(self,
channel: ChannelId,
client_can_do: bool,
session: Session)
-> Self::SessionUnit
channel: ChannelId,
client_can_do: bool,
session: Session)
-> Self::SessionUnit
The server informs this client of whether the client may perform control-S/control-Q flow control. See RFC4254.
fn exit_status(self,
channel: ChannelId,
exit_status: u32,
session: Session)
-> Self::SessionUnit
channel: ChannelId,
exit_status: u32,
session: Session)
-> Self::SessionUnit
The remote process has exited, with the given exit status.
fn exit_signal(self,
channel: ChannelId,
signal_name: Sig,
core_dumped: bool,
error_message: &str,
lang_tag: &str,
session: Session)
-> Self::SessionUnit
channel: ChannelId,
signal_name: Sig,
core_dumped: bool,
error_message: &str,
lang_tag: &str,
session: Session)
-> Self::SessionUnit
The remote process exited upon receiving a signal.
fn window_adjusted(self,
channel: ChannelId,
new_window_size: usize,
session: Session)
-> Self::SessionUnit
channel: ChannelId,
new_window_size: usize,
session: Session)
-> Self::SessionUnit
Called when the network window is adjusted, meaning that we
can send more bytes. This is useful if this client wants to
send huge amounts of data, for instance if we have called
Session::data
before, and it returned less than the
full amount of data.
