Expand description

Hints to the device about the memory allocation strategy.

Some backends may ignore these hints.

§suballocated_device_memory_block_size: Range<u64>

Defines the range of allowed memory block sizes for sub-allocated resources.

The backend may attempt to group multiple resources into fewer device memory blocks (sub-allocation) for performance reasons. The start of the provided range specifies the initial memory block size for sub-allocated resources. After running out of space in existing memory blocks, the backend may chose to progressively increase the block size of subsequent allocations up to a limit specified by the end of the range.

This does not limit resource sizes. If a resource does not fit in the specified range, it will typically be placed in a dedicated memory block.

Applications that have control over the content that is rendered (typically games) may find an optimal compromise between memory usage and performance by specifying the allocation configuration.
