Available on crate feature socks5 only.

Errors that can occur during SOCKS5 protocol operations.

Each variant represents a specific error condition that may arise when implementing or using the SOCKS5 protocol, as defined in RFC 1928 and RFC 1929.

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.

NoAcceptableAuthMethod

Server reports no acceptable authentication methods from those offered by client.

AuthenticationFailed

User credentials were rejected during authentication phase.

ConnectionFailed

Connection to the target host could not be established.

InvalidSocksVersion

Client sent an incorrect SOCKS version (expected 0x05).

InvalidAuthVersion

Client sent an incorrect authentication subprotocol version.

NoAuthMethods

Client did not provide any authentication methods.

NoSupportedAuthMethods

None of the client’s offered authentication methods are supported.

InvalidAuthMethod

The authentication method byte value is not recognized.

InvalidCommand

The command byte is not a valid SOCKS5 command.

InvalidReply

The reply byte is not a valid SOCKS5 reply code.

InvalidRsvValue

The reserved field contains a non-zero value.

InvalidUsernameEncoding

The username contains invalid UTF-8 encoding.

InvalidPasswordEncoding

The password contains invalid UTF-8 encoding.

UsernameTooLong

The username exceeds maximum allowed length (255 bytes).

PasswordTooLong

The password exceeds maximum allowed length (255 bytes).

TooManyAuthMethods

Client offered more than 255 authentication methods.

Trait Implementations

impl Clone for Socks5Error

fn clone(&self) -> Socks5Error

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Socks5Error

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

Formats the value using the given formatter.

impl Display for Socks5Error

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

Formats the value using the given formatter.

impl Error for Socks5Error

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<Socks5Error> for Error

fn from(e: Socks5Error) -> Self

Converts to this type from the input type.

impl PartialEq for Socks5Error

fn eq(&self, other: &Socks5Error) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
