Errors for vhost-user operations

Variants

BackendInternalError

Failure from the backend side.

ClientExit

client exited properly.

Disconnect

client disconnected. If connection is closed properly, use ClientExit instead.

EnterSuspendedState(Error)

FrontendInternalError

Failure from the frontend side.

IncorrectFds

Fd array in question is too big or too small

InvalidCastToInt(TryFromIntError)

Invalid cast to int.

InvalidMessage

Invalid message format, flag or content.

InvalidOperation

Unsupported operations due to that the protocol feature hasn’t been negotiated.

InvalidParam(&'static str)

Invalid parameters.

OversizedMsg

Message is too large

PartialMessage

Only part of a message have been sent or received successfully

RecvBufferTooSmall

Provided recv buffer was too small, and data was dropped.

Fields

got: usize

The size of the buffer received.

want: usize

The expected size of the buffer.

ReqHandlerError(Error)

Error from request handler

RestoreError(Error)

Failure to restore.

SnapshotError(Error)

Failure to snapshot.

SocketError(Error)

Generic socket errors.

SocketRetry(Error)

Should retry the socket operation again.

TubeError(TubeError)

Error from tx/rx on a Tube.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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

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.
