While the CTF reading libraries focus on decoding and providing completed and ordered event record objects, the yactfr API offers a lower level of CTF processing. Allowing iteration over individual element sequences to obtain elements: beginning/end of packet, beginning/end of event record, beggining/end of structure, individual data stream scalar values like fixed-length integers, fixed-length floating point numbers, and null-terminated strings, specific clock value update, known data stream ID, and the rest.
