Enum FatalError

#[non_exhaustive]
pub enum FatalError {
    Spawn {
        spawning: &'static str,
        cause: Arc<SpawnError>,
    },
    Keystore(Error),
    KeystoreRace {
        action: &'static str,
        path: ArtiPath,
    },
    MissingHsIdKeypair(HsNickname),
    IptKeysFoundUnexpectedly(ArtiPath),
    NetdirProviderShutdown(NetdirProviderShutdown),
    MissingField(UninitializedFieldError),
    RestrictedDiscoveryNoClients,
    Bug(Bug),
}

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)

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.

RestrictedDiscoveryNoClients

Available on crate feature restricted-discovery only.

Invalid restricted discovery configuration.

Bug(Bug)

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

Trait Implementations

impl Clone for FatalError

fn clone(&self) -> FatalError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FatalError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for FatalError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

impl Error for FatalError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting
