Enum MmioError 

pub enum MmioError {
    BadMagic(u32),
    UnsupportedVersion(u32),
    InvalidDeviceID(DeviceTypeError),
    MmioRegionTooSmall,
}

An error encountered initialising a VirtIO MMIO transport.

Variants

BadMagic(u32)

The header doesn’t start with the expected magic value 0x74726976.

UnsupportedVersion(u32)

The header reports a version number that is neither 1 (legacy) nor 2 (modern).

InvalidDeviceID(DeviceTypeError)

The header reports a device ID of 0.

MmioRegionTooSmall

The MMIO region size was smaller than the header size we expect.

Trait Implementations

impl Clone for MmioError

fn clone(&self) -> MmioError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MmioError

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

Formats the value using the given formatter.

impl Display for MmioError

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

Formats the value using the given formatter.

impl Error for MmioError

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 PartialEq for MmioError

fn eq(&self, other: &MmioError) -> 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.
