Enum MemoryAllocatorError

pub enum MemoryAllocatorError {
    AllocateDeviceMemory(Validated<VulkanError>),
    FindMemoryType,
    OutOfPoolMemory,
    DedicatedAllocationRequired,
    BlockSizeExceeded,
}

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

Variants

AllocateDeviceMemory(Validated<VulkanError>)

Allocating DeviceMemory failed.

FindMemoryType

Finding a suitable memory type failed.

This is returned from MemoryAllocator::allocate when MemoryAllocator::find_memory_type_index returns None.

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.

Trait Implementations

impl Clone for MemoryAllocatorError

fn clone(&self) -> MemoryAllocatorError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MemoryAllocatorError

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

Formats the value using the given formatter.

impl Display for MemoryAllocatorError

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

Formats the value using the given formatter.

impl Error for MemoryAllocatorError

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.
