Enum TunnelError 

pub enum TunnelError {
    HostKeyMismatch {
        host: String,
        port: u16,
        line: usize,
    },
    UnknownHost {
        host: String,
        port: u16,
        algorithm: String,
        fingerprint: String,
        key: Box<PublicKey>,
    },
    Session(String),
    Auth(String),
    Key(String),
    Channel(String),
    Russh(Error),
    Io(Error),
}

Errors raised by the tunnel layer.

From<russh::Error> is required by the russh::client::Handler associated Error bound, so the dedicated Russh variant is the conversion target — Session/Auth/Key/Channel are for diagnostics the tunnel layer raises itself.

Variants

HostKeyMismatch

Host key on file matches the server’s advertised key.

Fields

host: String

port: u16

line: usize

UnknownHost

Host not present in known_hosts — TOFU prompt required.

Fields

host: String

port: u16

algorithm: String

fingerprint: String

key: Box<PublicKey>

Boxed to keep TunnelError (and the Results that carry it) small now that the tunnel setup path is synchronous.

Session(String)

Auth(String)

Key(String)

Channel(String)

Russh(Error)

Io(Error)

Trait Implementations

impl Debug for TunnelError

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

Formats the value using the given formatter.

impl Display for TunnelError

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

Formats the value using the given formatter.

impl Error for TunnelError

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 TunnelError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for TunnelError

fn from(source: Error) -> Self

Converts to this type from the input type.
