+/// ## Arguments
+/// `transaction` - The pointer to a TariCompletedTransaction
+/// `error_out` - Pointer to an int which will be modified to an error code should one occur, may not be null. Functions
+/// as an out parameter.
+///
+/// ## Returns
+/// `*const c_char` - Returns the pointer to the char array, note that it will return a pointer
+/// to an empty char array if transaction is null
+///
+/// # Safety
+/// The ```string_destroy``` method must be called when finished with string coming from rust to prevent a memory leak
