#[non_exhaustive]
pub enum ProxyError { ProxyConnect(Arc<Error>), ProxyIo(Arc<Error>), InvalidSocksAddr(Error), UnrecognizedAddr, InvalidSocksRequest(Error), SocksProto(Error), Bug(Bug), UnexpectedData, SocksError(SocksStatus), }
Expand description

An error that occurs while negotiating a connection with a proxy.

Variants (Non-exhaustive)§

This enum is marked as 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.
§

ProxyConnect(Arc<Error>)

We had an IO error while trying to open a connection to the proxy.

§

ProxyIo(Arc<Error>)

We had an IO error while talking to the proxy.

§

InvalidSocksAddr(Error)

We tried to use an address which socks doesn’t support.

§

UnrecognizedAddr

We tried to use an address type which we don’t recognize.

§

InvalidSocksRequest(Error)

Our SOCKS implementation told us that this request cannot be encoded.

§

SocksProto(Error)

The peer refused our request, or spoke SOCKS incorrectly.

§

Bug(Bug)

We encountered an internal programming error.

§

UnexpectedData

We got extra data immediately after our handshake, before we actually sent anything.

This is not a bug in the calling code or in the peer protocol: it just means that the remote peer sent us data before we actually sent it any data. Unfortunately, there’s a limitation in our code that makes it discard any such data, and therefore we have to give this error to prevent bugs.

We could someday remove this limitation.

§

SocksError(SocksStatus)

The proxy told us that our attempt failed.
