Implementations

impl VirtqError

pub fn is_transient(&self) -> bool

Check if this error is transient or unrecoverable.

Trait Implementations

impl Debug for VirtqError

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

Formats the value using the given formatter.

impl Display for VirtqError

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

Formats the value using the given formatter.

impl Error for VirtqError

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<AllocError> for VirtqError

fn from(e: AllocError) -> Self

Converts to this type from the input type.

impl From<RingError> for VirtqError

fn from(e: RingError) -> Self

Converts to this type from the input type.
