Module rendy::memory

GPU memory management

Structs

Coherent	Coherent marker.
Data	Full speed GPU access. Optimal for render targets and persistent resources. Avoid memory with host access.
DedicatedAllocator	Dedicated memory allocator that uses memory object per allocation requested.
DedicatedBlock	Memory block allocated from DedicatedAllocator
Download	GPU to CPU data flow with mapping. Used for copying data from Data memory to be read by the host. Host access is guaranteed.
Dynamic	CPU to GPU data flow with update commands. Used for dynamic buffer data, typically constant buffers. Host access is guaranteed. Prefers memory with fast GPU access.
DynamicAllocator	No-fragmentation allocator. Suitable for any type of small allocations. Every freed block can be reused.
DynamicBlock	Memory block allocated from DynamicAllocator
DynamicConfig	Config for DynamicAllocator.
Heaps	Heaps available on particular physical device.
HeapsConfig	Config for Heaps allocator.
LinearAllocator	Linear allocator that return memory from chunk sequentially. It keeps only number of bytes allocated from each chunk. Once chunk is exhausted it is placed into list. When all blocks allocated from head of that list are freed, head is freed as well.
LinearBlock	Memory block allocated from LinearAllocator
LinearConfig	Config for LinearAllocator.
MappedRange	Represents range of the memory mapped to the host. Provides methods for safer host access to the memory.
MaybeCoherent	Value that contains either coherent marker or non-coherent marker.
Memory	Memory object wrapper. Contains size and properties of the memory.
MemoryBlock	Memory block allocated from Heaps.
MemoryHeapUtilization	Memory utilization of one heap.
MemoryTypeUtilization	Memory utilization of one type.
MemoryUtilization	Memory utilization stats.
NonCoherent	Non-coherent marker.
TotalMemoryUtilization	Total memory utilization.
Upload	CPU to GPU data flow with mapping. Used for staging data before copying to the Data memory. Host access is guaranteed.

Enums

HeapsError	Possible errors returned by Heaps.
Kind	Allocator kind.
MemoryUsageValue	Well-known memory usage types.

Traits

Allocator	Allocator trait implemented for various allocators.
Block	Block that owns a Range of the Memory. Implementor must ensure that there can't be any other blocks with overlapping range (either through type system or safety notes for unsafe functions). Provides access to safe memory range mapping.
MemoryUsage	Memory usage trait.
Write	Trait for memory region suitable for host writes.
