Error type for external users

Variants§

§

BaseNotDirectory

The fd given as a base was not a directory so the operation was not possible

§

NotAFile

Expected a file but found not a file

§

InvalidFd

The fd given was not usable

§

AlreadyExists

File exists

§

Lock

The filesystem has failed to lock a resource.

§

IOError

Something failed when doing IO. These errors can generally not be handled. It may work if tried again.

§

AddressInUse

The address was in use

§

AddressNotAvailable

The address could not be found

§

BrokenPipe

A pipe was closed

§

ConnectionAborted

The connection was aborted

§

ConnectionRefused

The connection request was refused

§

ConnectionReset

The connection was reset

§

Interrupted

The operation was interrupted before it could finish

§

InvalidData

Invalid internal data, if the argument data is invalid, use InvalidInput

§

InvalidInput

The provided data is invalid

§

NotConnected

Could not perform the operation because there was not an open connection

§

EntryNotFound

The requested file or directory could not be found

§

NoDevice

The requested device couldn’t be accessed

§

PermissionDenied

Caller was not allowed to perform this operation

§

TimedOut

The operation did not complete within the given amount of time

§

UnexpectedEof

Found EOF when EOF was not expected

§

WouldBlock

Operation would block, this error lets the caller know that they can try again

§

WriteZero

A call to write returned 0

§

DirectoryNotEmpty

Directory not Empty

§

StorageFull

§

UnknownError

Some other unhandled error. If you see this, it’s probably a bug.
