+// GetFunctionName returns the name of a function from its reference.
+//
+// This function uses reflection to get the function's pointer and
+// retrieves its name using the runtime package. It can be used to
+// dynamically obtain the name of a function at runtime.
+//
+// Parameters:
+//   - fn (any): A reference to the function whose name you want to retrieve.
+//
+// Returns:
+//   - string: The name of the function, typically in the form of "packageName.funcName".
+//
+// Example usage:
+//
+//	func example() {}
+//	name := utils.GetFunctionName(example) // Returns "main.example"
+func GetFunctionName(fn any) string {
+	// Get the pointer to the function using reflection
+	pc := reflect.ValueOf(fn).Pointer()
+
+	// Use the pointer to get the function object
+	funcObj := runtime.FuncForPC(pc)
+
+	// Return the name of the function
+	return funcObj.Name()
+}
+
+// DefaultValue checks if a given value is non-empty and returns it.
+// If the value is empty, it returns a fallback (default) value.
+//
+// Parameters:
+//   - value (string): The value to check for non-emptiness.
+//   - other (string): The fallback value to return if the input `value` is empty.
+//
+// Returns:
+//   - string: The `value` if it is non-empty, otherwise the `other` value.
+//
+// Example usage:
+//
+//	result := utils.DefaultValue("", "default")  // Returns "default"
+//	result := utils.DefaultValue("custom", "default") // Returns "custom"
+func DefaultValue(value string, other string) string {
+	// Return `value` if it is not empty, otherwise return `other`
+	if value != "" {
+		return value
+	}
+	return other
