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.

`DirTimeout`

The directory cache took too long to reply to us.

`TruncatedHeaders`

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

`ResponseTooLong(usize)`

Received a response that was longer than we expected.

`Utf8Encoding(FromUtf8Error)`

Data received was not UTF-8 encoded.

`IoError(Arc<Error>)`

Io error while reading on connection

`Proto(Error)`

A protocol error while launching a stream

`HttparseError(Error)`

Error when parsing http

`HttpError(Arc<Error>)`

Error while creating http request

`ContentEncoding(String)`

Unrecognized content-encoding

`TooMuchClockSkew`

Too much clock skew between us and the directory.

(We’ve givin up on this request early, since any directory that it believes in, we would reject as untimely.)

`MdSha256Empty`

The requested SHA256 digest of microdescriptors is empty.
