Enum TransportError

}

Transport layer errors (SSH connection, authentication, I/O).

Variants

Connect(String)

Failed to establish TCP/SSH connection.

Auth(String)

SSH authentication rejected.

Channel(String)

SSH channel or subsystem error.

ChannelClosed(String)

SSH channel was closed by the remote side (device reboot, SSH timeout, network interruption).

This is the most common transport failure during an active session. Callers should reconnect().

Io(Error)

General I/O error on the transport.

Ssh(String)

SSH library error.

HostKeyMismatch

Server presented a host key whose fingerprint does not match the one recorded in the known_hosts file for this host. Possible MITM attack or the device’s host key was rotated — investigate before reconnecting.

Fields

host: String

expected: String

actual: String

HostKeyNotInKnownHosts

No entry for this host exists in the known_hosts file. Fail closed — pre-populate the file with ssh-keyscan before connecting.

Fields

host: String

port: u16

path: String

HostKeyRevoked

The known_hosts file contains an @revoked entry for the host key presented by the server. Fail closed.

Fields

host: String

Trait Implementations

impl Debug for TransportError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for TransportError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for TransportError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Error> for TransportError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<TransportError> for NetconfError

fn from(source: TransportError) -> Self

Converts to this type from the input type.
