Enum Exception

pub enum Exception {
    Failure(DeviceFailure),
    Error(Seq, Seq, WorkerError),
}

An exception to commanded execution, exposed to the client.

Variants

Failure(DeviceFailure)

A failure is a non-deterministic problem with the underlying device or its infrastructure. For example, a controller may enter a crash loop, or its GPU may be lost

Error(Seq, Seq, WorkerError)

A deterministic problem with the user’s code. For example, an OOM resulting in trying to allocate too much GPU memory, or violating some invariant enforced by the various APIs.

Implementations

impl Exception

pub fn is_failure(&self) -> bool

Returns true if this is a Exception::Failure, otherwise false

pub fn as_failure_mut(&mut self) -> Option<&mut DeviceFailure>

Optionally returns mutable references to the inner fields if this is a Exception::Failure, otherwise None

pub fn as_failure(&self) -> Option<&DeviceFailure>

Optionally returns references to the inner fields if this is a Exception::Failure, otherwise None

pub fn into_failure(self) -> Result<DeviceFailure, Self>

Returns the inner fields if this is a Exception::Failure, otherwise returns back the enum in the Err case of the result

pub fn is_error(&self) -> bool

Returns true if this is a Exception::Error, otherwise false

pub fn as_error_mut(&mut self) -> Option<(&mut Seq, &mut Seq, &mut WorkerError)>

Optionally returns mutable references to the inner fields if this is a Exception::Error, otherwise None

pub fn as_error(&self) -> Option<(&Seq, &Seq, &WorkerError)>

Optionally returns references to the inner fields if this is a Exception::Error, otherwise None

pub fn into_error(self) -> Result<(Seq, Seq, WorkerError), Self>

Returns the inner fields if this is a Exception::Error, otherwise returns back the enum in the Err case of the result

Trait Implementations

impl Clone for Exception

fn clone(&self) -> Exception

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Exception

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Exception

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Exception

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

Formats the value using the given formatter.

impl Error for Exception

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<DeviceFailure> for Exception

fn from(source: DeviceFailure) -> Self

Converts to this type from the input type.

impl PartialEq for Exception

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

impl Serialize for Exception

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
