An error encountered initialising a VirtIO PCI transport.

Variants

InvalidDeviceId(u16)

PCI device ID was not a valid VirtIO device ID.

InvalidVendorId(u16)

PCI device vender ID was not the VirtIO vendor ID.

MissingCommonConfig

No valid VIRTIO_PCI_CAP_COMMON_CFG capability was found.

MissingNotifyConfig

No valid VIRTIO_PCI_CAP_NOTIFY_CFG capability was found.

InvalidNotifyOffMultiplier(u32)

VIRTIO_PCI_CAP_NOTIFY_CFG capability has a notify_off_multiplier that is not a multiple of 2.

MissingIsrConfig

No valid VIRTIO_PCI_CAP_ISR_CFG capability was found.

UnexpectedIoBar

An IO BAR was provided rather than a memory BAR.

BarNotAllocated(u8)

A BAR which we need was not allocated an address.

BarOffsetOutOfRange

The offset for some capability was greater than the length of the BAR.

Misaligned

The address was not aligned as expected.

Fields

address: usize

The address in question.

alignment: usize

The expected alignment in bytes.

Pci(PciError)

A generic PCI error,

Trait Implementations

impl Clone for VirtioPciError

fn clone(&self) -> VirtioPciError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VirtioPciError

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

Formats the value using the given formatter.

impl Display for VirtioPciError

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

Formats the value using the given formatter.

impl Error for VirtioPciError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<PciError> for VirtioPciError

fn from(error: PciError) -> Self

Converts to this type from the input type.

impl PartialEq for VirtioPciError

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

Tests for self and other values to be equal, and is used by ==.

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

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