### Is this a duplicate?

- [X] I confirmed there appear to be no [duplicate issues](https://github.com/NVIDIA/cccl/issues) for this bug and that I agree to the [Code of Conduct](CODE_OF_CONDUCT.md)

### Is this for new documentation, or an update to existing docs?

Update

### Describe the incorrect/future/missing documentation

When I navigate to a widely used data structure such as host_vector:
https://nvidia.github.io/cccl/thrust/api/classes/classthrust_1_1host__vector.html

That page looks like it intends to list member functions, but it is missing basic things like size().

I would rather not have to navigate to view the source code myself which is here:
https://github.com/NVIDIA/cccl/blob/main/thrust/thrust/host_vector.h

I would suggest at least linking to the appropriate source page.

### If this is a correction, please provide a link to the incorrect documentation. If this is a new documentation request, please link to where you have looked.
