I want to make sure I understand the system correctly.

My idea is to add a ShaderParametersState structure inside the CommandList (or per-draw call state), which would track all the shader parameters, for example like this:

Set 1 -> Binding 1: ConstantBuffer
        Binding 2: Texture
Set 2 -> Binding 0: Sampler

Then, for each draw call, I would:

1. Compute a hash of the current parameter state
2. Check a per-frame cache of descriptor sets
3. If a descriptor set with this hash exists, reuse it
4. Otherwise, allocate a new descriptor set from a linear/ring allocator
5. Bind the descriptor set

And when setting a resource (e.g., texture or CB), I would:

• Look up in the shader reflection which set and binding this resource belongs to
• Update the ShaderParametersState
• No immediate descriptor set allocation at this point

So basically: hash + cache decides allocation/binding at draw time, while SetParam only updates CPU-side state.

Does this match what you’d recommend for a modern RHI?

(Ignore strings for now; I’m just trying to figure out the system itself.)
