Overview of the GPU cache.
The main goal of the GPU cache is to allow on-demand allocation and construction of GPU resources for the vertex shaders to consume.
Every item that wants to be stored in the GPU cache should create a GpuCacheHandle that is used to refer to a cached GPU resource. Creating a handle is a cheap operation, that does not allocate room in the cache.
On any frame when that data is required, the caller
must request that handle, via
request. If the
data is not in the cache, the user provided closure
will be invoked to build the data.
end_frame has occurred, callers can
get_address API to get the allocated
address in the GPU cache of a given resource slot
for this frame.
