Functions

allocate MemAlloc allocate(MemoryRequirements requirements, AllocOptions options): Allocate memory for the given requirements
allocateBuffer BufferAlloc allocateBuffer(BufferUsage usage, size_t size, AllocOptions options): Create a buffer, then allocate and bind memory for its requirements
allocateImage ImageAlloc allocateImage(ImageInfo info, AllocOptions options): Create an image, then allocate and bind memory for its requirements
collectStats AllocStats collectStats(): Undocumented in source. Be warned that the author may not have intended to support it.
dispose void dispose(): Undocumented in source. Be warned that the author may not have intended to support it.
tryAllocate bool tryAllocate(MemoryRequirements requirements, uint memoryTypeIndex, AllocOptions options, ResourceLayout layout, AllocResult result): Attempt to allocate memory for the given index and for given requirements. If successful, result is filled with necessary data.
