Enum tor_socksproto::Error

#[non_exhaustive]
pub enum Error {
    Truncated,
    Syntax,
    BadProtocol(u8),
    NoSupport,
    AlreadyFinished,
    Internal,
}

An error that occurs while negotiating a SOCKS handshake.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Truncated

Tried to handle a message what wasn’t complete: try again.

Syntax

The SOCKS client didn’t implement SOCKS correctly.

(Or, more likely, we didn’t account for its behavior.)

BadProtocol(u8)

The SOCKS client declared a SOCKS version number that isn’t one we support.

In all likelihood, this is somebody trying to use the port for some protocol other than SOCKS.

Tuple Fields of BadProtocol

0: u8

NoSupport

The SOCKS client tried to use a SOCKS feature that we don’t support at all.

AlreadyFinished

Tried to progress the SOCKS handshake when it was already finished. This is a programming error.

Internal

Something went wrong with the programming of this module.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

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

impl From<Error> for Error

fn from(e: Error) -> Error

Performs the conversion.
