Enum VirtioError 

#[non_exhaustive]
pub enum VirtioError {
    Memory(Error),
    Queue(QueueError),
    Irq(String),
    Activate(ActivateError),
    Io(Error),
    MalformedPayload(String),
    InvalidTransition(&'static str),
}

Errors produced by the virtio transport, queue handling, or device frontends.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Memory(Error)

Guest memory access failed (range escape, region overflow).

Queue(QueueError)

A queue setup or descriptor-walk error.

Irq(String)

Failed to deliver an IRQ to the GIC.

Activate(ActivateError)

Device-level activation failure (resource unavailable, configuration mismatch).

Io(Error)

I/O backend error (host file, network socket, …).

MalformedPayload(String)

Device received a malformed descriptor or request payload.

InvalidTransition(&'static str)

Device received a write to a register that is invalid in the current state machine state (e.g. configuring a queue after DRIVER_OK).

Trait Implementations

impl Debug for VirtioError

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

Formats the value using the given formatter.

impl Display for VirtioError

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

Formats the value using the given formatter.

impl Error for VirtioError

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.
