Invalid ordered residency-window configuration or accounting.

Variants

EmptyLayerWindow

A layer window had no units.

OversizedLayerWindow

A device window depth was zero or exceeded its unit count.

Fields

depth: usize

Requested resident-unit bound.

layer_count: usize

Available ordered units.

InvalidLayerIndex

A requested current unit was outside the sequence.

Fields

index: usize

Requested index.

layer_count: usize

Available ordered units.

DuplicateLayerWindowUnit

An ordered layer window repeated a unit identifier.

Fields

id: OffloadUnitId

Duplicated identifier.

InvalidGroupId

A named execution group had an empty identifier.

ArithmeticOverflow

Checked group accounting overflowed.

Fields

context: &'static str

Calculation that overflowed.

Trait Implementations

impl Clone for ResidencyWindowError

fn clone(&self) -> ResidencyWindowError

impl Eq for ResidencyWindowError

impl Error for ResidencyWindowError

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 ResidencyWindowError

fn eq(&self, other: &ResidencyWindowError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
