| // SafePtr is a function that takes a pointer of any type (T) as an argument. |
| // If the provided pointer is not nil, it returns the same pointer. If it is nil, it returns nil instead. |
| // |
| // This function is particularly useful to prevent nil pointer dereferencing when: |
| // |
| // - The type implements interfaces that are called by the logger, such as `fmt.Stringer`. |
| // - And these interface implementations do not perform nil checks themselves. |
