Enum vulkano::memory::allocator::AllocationCreationError

pub enum AllocationCreationError {
    VulkanError(VulkanError),
    OutOfPoolMemory,
    DedicatedAllocationRequired,
    BlockSizeExceeded,
    SuballocatorBlockSizeExceeded,
}

Error that can be returned when creating an allocation using a memory allocator.

Variants

VulkanError(VulkanError)

OutOfPoolMemory

There is not enough memory in the pool.

This is returned when using MemoryAllocatePreference::NeverAllocate and there is not enough memory in the pool.

DedicatedAllocationRequired

A dedicated allocation is required but was explicitly forbidden.

This is returned when using MemoryAllocatePreference::NeverAllocate and the implementation requires a dedicated allocation.

BlockSizeExceeded

The block size for the allocator was exceeded.

This is returned when using MemoryAllocatePreference::NeverAllocate and the allocation size exceeded the block size for all heaps of suitable memory types.

SuballocatorBlockSizeExceeded

The block size for the suballocator was exceeded.

This is returned when using GenericMemoryAllocator<Arc<PoolAllocator<BLOCK_SIZE>>> if the allocation size exceeded BLOCK_SIZE.

Trait Implementations

impl Clone for AllocationCreationError

fn clone(&self) -> AllocationCreationError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AllocationCreationError

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

Formats the value using the given formatter.

impl Display for AllocationCreationError

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

Formats the value using the given formatter.

impl Error for AllocationCreationError

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

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, demand: &mut Demand<'a>)

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

Provides type based access to context intended for error reports.

impl From<AllocationCreationError> for BufferError

fn from(err: AllocationCreationError) -> Self

Converts to this type from the input type.

impl From<AllocationCreationError> for ImageError

fn from(err: AllocationCreationError) -> Self

Converts to this type from the input type.

impl From<AllocationCreationError> for ImmutableImageCreationError

fn from(err: AllocationCreationError) -> Self

Converts to this type from the input type.

impl From<VulkanError> for AllocationCreationError

fn from(err: VulkanError) -> Self

Converts to this type from the input type.

impl PartialEq<AllocationCreationError> for AllocationCreationError

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
