Where is the best place to store global structures?

Question

go

Where is the best place to store global structures in a project? At the root of the project? Or nevertheless to thrust in internal?
The structure is standard:
-cmd
-internal -> or is it better to put structures here?
-pkg
-go.mod
-go.sum
-server.go
-|user.go //structure
-|todo.go //structure

Answer 1

If we take the standard project structure, I would start from whether it makes sense to make this structure available. If yes, then I would look towards /pkg, if not /internal.
On a good note, I would make a separate package for this structure, and depending on whether it is used internally or not - I would put the package in /pkg or in /internal
What is your global structure used for?
