Is it possible to have a circular dependency in rust workspaces when crates are not usable by themselves?

the problem with circular dependencies is that you can’t build one as it needs the other

but I don’t care to have a single target that is built all at once like it was a single project

Why use workspaces in the first place?

Let’s say I have this structure:

- crates:
  - storage:
    - hash_table
    - b_tree
    - buffer_pool
  - catalog

Visibility:

I want to mark some function visibility to be inside that crate (e.g. only inside b_tree) I need to do pub(in crate::storage:b_tree) everywhere (having 2 layers is ok but what about 4?)

Imports:

I want to use some function from other “crate” it will require me to have the full structure crate::storage::b_tree or have to propagate the use up the tree
