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.

`NoDownloadSupport`

This DirMgr doesn’t support downloads.

`BadArgument(&'static str)`

A bad argument was provided to some configuration function.

`CacheCorruption(&'static str)`

We couldn’t read something from disk that we should have been able to read.

`SqliteError(Error)`

rusqlite gave us an error.

`UnrecognizedSchema`

A schema version that says we can’t read it.

`UpdaterShutdown`

An updater no longer has anything to update.

`BadNetworkConfig(&'static str)`

We couldn’t configure the network.

`DirectoryNotPresent`

User requested an operation that required a usable bootstrapped directory, but we didn’t have one.

`CacheIsLocked`

Another process has locked the store for writing.

`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.

`RuntimeError(String)`

An error emitted by the runtime. The argument is the formatted error of the runtime.

`StorageError(String)`

Blob storage error

`ConsensusDiffError(Error)`

An error given by the consensus diff crate.

`StringParsingError(String)`

A string parsing error.

`NetDocError(Error)`

An error given by the network document crate.

`DirClientError(Error)`

An error given by dirclient

`SignatureError(Error)`

An error given by the checkable crate.

`IOError(Error)`

An IO error occurred while manipulating storage on disk.
