Enum gpu_alloc::Dedicated

#[non_exhaustive]
pub enum Dedicated {
    Required,
    Preferred,
}

Hints for allocator to decide on allocation strategy.

Variants (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.
