Handle
VkBufferCollectionFUCHSIA
Opaque handle to a buffer collection object
Fuchsia’s FIDL-based Sysmem service interoperates with Vulkan via the VK_FUCHSIA_buffer_collection extension.
A buffer collection is a set of one or more buffers which were allocated together as a group and which all have the same properties. These properties describe the buffers' internal representation, such as its dimensions and memory layout. This ensures that all of the buffers can be used interchangeably by tasks that require swapping among multiple buffers, such as double-buffered graphics rendering.
On Fuchsia, the Sysmem service uses buffer collections as a core construct in its design.
Buffer collections are represented by VkBufferCollectionFUCHSIA
