Variants

OomError(OomError)

Not enough memory available.

TooManyObjects

The maximum number of allocations has been exceeded.

MemoryMapError(MemoryMapError)

An error occurred when mapping the memory.

ExtensionNotEnabled

Fields

extension: &'static str

reason: &'static str

FeatureNotEnabled

Fields

feature: &'static str

reason: &'static str

DedicatedAllocationSizeMismatch

Fields

allocation_size: DeviceSize

required_size: DeviceSize

dedicated_allocation was Some, but the provided allocation_size was different from the required size of the buffer or image.

ImportFdHandleTypeNotSupported

Fields

handle_type: ExternalMemoryHandleType

The provided MemoryImportInfo::Fd::handle_type is not supported for file descriptors.

MemoryTypeHeapSizeExceeded

Fields

allocation_size: DeviceSize

heap_size: DeviceSize

The provided allocation_size was greater than the memory type’s heap size.

MemoryTypeIndexOutOfRange

Fields

memory_type_index: u32

memory_type_count: u32

The provided memory_type_index was not less than the number of memory types in the physical device.

SpecViolation(u32)

Spec violation, containing the Valid Usage ID (VUID) from the Vulkan spec.

ImplicitSpecViolation(&'static str)

An implicit violation that’s convered in the Vulkan spec.

Trait Implementations

impl Clone for DeviceMemoryAllocationError

fn clone(&self) -> DeviceMemoryAllocationError

Returns a copy of the value.

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

impl Error for DeviceMemoryAllocationError

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

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

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
