A Vulkan driver failure or a missing command (entry, instance or device level).

Variants

EnumerationUnstable

The native enumeration did not stabilize within the bounded retry budget.

Fields

attempts: u32

InitializationFailed(InitializationFailure)

Native creation succeeded but cleanup could not be resolved. Handle this variant explicitly to recover the still-live object and retained library.

Vulkan(Result)

MissingCommand(&'static str)

InvalidMetadata(&'static str)

Invalid caller-supplied creation/import metadata; no native effect occurred.

FeatureNotEnabled

A required exact feature-record member is disabled or unrecorded.

Fields

structure: StructureType

member: &'static str

HostAllocationFailed

InvalidOutput(&'static str)

CountOverflow(usize)

SliceLengthMismatch

An output/parallel slice does not match its native input count.

Fields

parameter: &'static str

expected: usize

actual: usize

Trait Implementations

impl Debug for CallError

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

Formats the value using the given formatter.

impl Display for CallError

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

Formats the value using the given formatter.

impl Error for CallError

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<CallError> for AllocError

fn from(error: CallError) -> Self

Converts to this type from the input type.

impl From<Result> for CallError

fn from(r: Result) -> Self

Lift a non-success VkResult into a CallError.

Callers that only expect VK_SUCCESS can use ? on a vk::Result once it is inside a Result<_, CallError> context.

impl PartialEq for CallError

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

Equality operator ==.

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

Inequality operator !=.

impl StructuralPartialEq for CallError
