Expand description

An error which can be returned when connecting to a destination host via SOCKS5 proxy server.

This error is used as the error type for the connect function.

Variants§

§

UnsupportedVersion(u8)

The server returned a version number that is not supported by this client. The actual version number received is returned as a payload of this variant.

§

UnsupportedMethod(u8)

The server selected a method that is not supported by this client. The actual method selected is returned as a payload of this variant. 0xff means that the server said none of the methods listed by the client were acceptable.

§

GeneralServerFailure

General SOCKS server failure.

§

HostUnreachable

Host unreachable.

§

ConnectionRefused

Connection refused.

§

TtlExpired

TTL expired.

§

CommandNotSupported

Command not supported.

§

AddressTypeNotSupported

Address type not supported.

§

UnknownFailure(u8)

Unknown failure. The actual reply value received is returned as a payload of this variant.

§

UnsupportedAddressType(u8)

The server returned a address type that is not supported by this client. The actual address type received is returned as a payload of this variant.

§

IoError(Error)

A standard I/O error was caught during communication with the server. The actual error caught is returned as a payload of this variant.

§

InvalidUsernameLength(usize)

The length of the username was invalid. The actual length supplied is returned as a payload of this variant.

§

InvalidPasswordLength(usize)

The length of the password was invalid. The actual length supplied is returned as a payload of this variant.

§

UnsupportedSubnegotiationVersion(u8)

The server returned a subnegotiation version number that is not supported by this client. The actual version number received is returned as a payload of this variant.

§

AuthenticationFailure

Authentication failure.
