Variants§

EventFd(Error)

Error while handling an Event file descriptor: {0}

InterruptError(InterruptError)

Received error while sending an interrupt: {0}

InvalidSize(u64)

Size {0} is invalid: it must be a multiple of block size and less than the total size

DeviceNotActive

Device is not active

UnexpectedWriteOnlyDescriptor

Descriptor is write-only

DescriptorWriteFailed

Error reading virtio descriptor

DescriptorReadFailed

Error writing virtio descriptor

UnknownRequestType(u32)

Unknown request type: {0}

DescriptorChainTooShort

Descriptor chain is too short

DescriptorLengthTooSmall

Descriptor is too small

UnexpectedReadOnlyDescriptor

Descriptor is read-only

InvalidAvailIdx(InvalidAvailIdx)

Error popping from virtio queue: {0}

QueueError(QueueError)

Error adding used queue: {0}

InvalidRange(RequestedRange)

Invalid requested range: {0:?}.

PlugRequestBlockStateInvalid(BlockRangeState)

The requested range cannot be plugged because it’s {0:?}.
