6/// Defines an error caused by the use of an incorrect index in one of the 
7/// structures exchanged during a pipeline. This is an internal error that 
8/// only occurs if there is a bug in the algorithms ensuring the consistency 
9/// of this data, and it cannot be recovered from except by abandoning the 
10/// ongoing process and report an error. However, it is preferred over panicking 
11/// to ensure safe usage of the library (please document an issue in this case,
12/// providing the message available in this struct).
