Expand description

An error which means we cannot continue to try to operate an onion service.

These errors only occur during operation, and only for catastrophic reasons (such as the async reactor shutting down).

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.
§

Spawn

Unable to spawn task

Fields

§spawning: &'static str

What we were trying to spawn

§cause: Arc<SpawnError>

What happened when we tried to spawn it.

§

Keystore(Error)

Failed to access the keystore.

§

KeystoreRace

Failed to access the keystore due to incompatible concurrent access.

This can only happen if someone is modifying the contents of the keystore just as we are trying to access it.

Fields

§action: &'static str

What action we were trying to perform

§path: ArtiPath

The ArtiPath we were trying to access

§

MissingHsIdKeypair(HsNickname)

The identity keypair of the service could not be found in the keystore.

§

IptKeysFoundUnexpectedly(ArtiPath)

IPT keys found for being-created IPT

This could only happen if someone is messing with our RNG or our code is completely wrong, or something.

§

NetdirProviderShutdown(NetdirProviderShutdown)

The network directory provider is shutting down without giving us the netdir we asked for.

§

MissingField(UninitializedFieldError)

A field was missing when we tried to construct a OnionService.

§

HsDescTooLong

Descriptor was too long to upload

§

Bug(Bug)

An error caused by a programming issue . or a failure in another library that we can’t work around.
