public fun assert_same_module_as_witness<T, Witness>()
public fun assert_same_module_as_witness<T, Witness>()First generic T is any type, second generic is Witness.
Witness is a type always in form "struct Witness has drop {}"
In this method, we check that T is exported by the same module.
That is both package ID, package name and module name must match.
Additionally, with accordance to the convention above, the second
generic Witness must be named Witness as a type.
Example
It's useful to assert that a one-time-witness is exported by the same
contract as Witness.
That's because one-time-witness is often used as a convention for
initiating e.g. a collection name.
However, it cannot be instantiated outside of the init function.
Therefore, the collection contract can export Witness which serves as
an auth token at a later stage.
