Device work queue planning errors.

Variants

ZeroCapacity

Queue capacity must be non-zero.

ZeroEntryBytes

Entry ABI width must be explicit and non-zero.

ZeroDrainChunk

Device-side drain chunk size must be non-zero.

InitialItemsExceedCapacity

Initial queue contents exceed capacity.

Fields

initial_items: u64

Initial active items.

queue_capacity: u64

Queue capacity.

HostParticipationRejected

Host participation would reintroduce CPU orchestration.

ByteCountOverflow

Byte arithmetic overflowed.

Fields

field: &'static str

Field being computed.

OverBudget

Queue does not fit the explicit device budget.

Fields

required_bytes: u64

Required bytes.

budget_bytes: u64

Budget bytes.

Trait Implementations

impl Clone for DeviceWorkQueueError

fn clone(&self) -> DeviceWorkQueueError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeviceWorkQueueError

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

Formats the value using the given formatter.

impl Display for DeviceWorkQueueError

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

Formats the value using the given formatter.

impl Eq for DeviceWorkQueueError

impl Error for DeviceWorkQueueError

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 DeviceWorkQueueError

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