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

`EntityNotFound`

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

`UnknownError`

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