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.
Unwanted(&'static str)
We received a document we didn’t want at all.
NetDirOlder
The NetDir we downloaded is older than the one we already have.
NoDownloadSupport
This DirMgr doesn’t support downloads.
CacheCorruption(&'static str)
We couldn’t read something from disk that we should have been able to read.
SqliteError(Arc<Error>)
rusqlite gave us an error.
ReadOnlyStorage(ReadOnlyStorageError)
Error while creating a read-only store.
UnrecognizedSchema
A schema version that says we can’t read it.
Fields
DirectoryNotPresent
User requested an operation that required a usable bootstrapped directory, but we didn’t have one.
UnrecognizedAuthorities
A consensus document is signed by an unrecognized authority set.
ManagerDropped
A directory manager has been dropped; background tasks can exit too.
CantAdvanceState
We made a bunch of attempts, but weren’t unable to advance the state of a download.
LockFile(Arc<Error>)
Error while accessing a lockfile.
CacheFile
Error while accessing a file in the store.
Fields
ConsensusDiffError(Error)
An error given by the consensus diff crate.
BadUtf8FromDirectory(FromUtf8Error)
Invalid UTF8 in directory response.
BadUtf8InCache(Utf8Error)
Invalid UTF8 from our cache.
BadHexInCache(FromHexError)
Invalid hexadecimal value in the cache.
BadJsonInCache(Arc<Error>)
Invalid json value in the cache
NetDocError
An error given by the network document crate.
ConsensusInvalid
An error indicating that the consensus could not be validated.
This kind of error is only returned during the certificate fetching state; it indicates that a consensus which previously seemed to be plausible has turned out to be wrong after we got the certificates.
UntimelyObject(TimeValidityError)
An error caused by an expired or not-yet-valid object.
DirClientError(Error)
An error given by dirclient
SignatureError(Arc<Error>)
An error given by the checkable crate.
OfflineMode
An attempt was made to bootstrap a DirMgr created in offline mode.
CacheAccess(Error)
A problem accessing our cache directory (for example, no such directory)
CachePermissions(Error)
👎Deprecated: use Error::CacheAccess instead
A problem accessing our cache directory (for example, no such directory)
This variant name is misleading - see the docs for fs_mistrust::Error.
Please use Error::CacheAccess instead.
Spawn
Unable to spawn task
Fields
§
cause: Arc<SpawnError>What happened when we tried to spawn it
ExternalDirProvider
Other error from an external directory provider
Bug(Bug)
A programming problem, either in our code or the code calling it.
