Ensuring Post-Instantiation Method Invocation in Go

In Go, the standard Close method is optional after object creation. This can lead to resource leaks or other issues if not invoked properly. Here's a discussion on how to address this concern:

Direct Enforcement

Go does not have a mechanism to enforce the mandatory invocation of a method after object creation.

Indirect Approaches

1. Proper Documentation: Clearly document that the Close method must be called post-instantiation for effective resource management.
2. Unexported Type: Consider making the struct unexported and providing an exported constructor function that initializes the struct and ensures the proper calling of Close.
3. Custom Scavenging: The runtime.SetFinalizer() function can be used to register a finalizer function that will be executed when an object becomes unreachable. However, there is no guarantee that the function will be executed before program termination.

Conclusion

While there are no direct methods to enforce mandatory method calls in Go, proper documentation and indirect approaches can help encourage responsible resource management and minimize potential issues.
