}

The error type of VirtIO drivers.

Variants

QueueFull

There are not enough descriptors available in the virtqueue, try again later.

NotReady

The device is not ready.

WrongToken

The device used a different descriptor chain to the one we were expecting.

AlreadyUsed

The queue is already in use.

InvalidParam

Invalid parameter.

DmaError

Failed to alloc DMA memory.

IoError

I/O Error

ConfigSpaceTooSmall

The config space advertised by the device is smaller than the driver expected.

ConfigSpaceMissing

The device doesn’t have any config space, but the driver expects some.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq<Error> for Error

fn eq(&self, other: &Error) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
