Hints for allocator to decide on allocation strategy.
Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
Required
Allocation directly from device.
Very slow.
Count of allocations is limited.
Use with caution.
Must be used if resource has to be bound to dedicated memory object.
Preferred
Hint for allocator that dedicated memory object is preferred.
Should be used if it is known that resource placed in dedicated memory object
would allow for better performance.
Implementation is allowed to return block to shared memory object.
