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.

`CompressionBomb`

We received an object with a suspiciously good compression ratio

`DirTimeout`

The directory cache took too long to reply to us.

`TruncatedHeaders`

We got an EOF before we were done with the headers.

`HttpStatus(Option<u16>)`

Tuple Fields

0: Option<u16>

Got an HTTP status other than 200

`ResponseTooLong(usize)`

Tuple Fields

0: usize

Received a response that was longer than we expected.

`Utf8Encoding(FromUtf8Error)`

Tuple Fields

0: FromUtf8Error

Data received was not UTF-8 encoded.

`IoError(Error)`

Tuple Fields

0: Error

Io error while reading on connection

`Proto(Error)`

Tuple Fields

0: Error

A protocol error while launching a stream

`CircMgr(Error)`

Tuple Fields

0: Error

Error while getting a circuit

`HttparseError(Error)`

Tuple Fields

0: Error

Error when parsing http

`HttpError(Error)`

Tuple Fields

0: Error

Error while creating http request

`ContentEncoding(String)`

Tuple Fields

0: String

Unrecognized content-encoding
