struct MNALIB::MnaNode

One operation in the computational graph.

Single executable step in an MNA pipeline graph, with attributes, typed ports, exec mode, verification and provenance.

const MnaPort sourceOut = port("out", MnaPortDir::Output); // name, data kind, direction
source.outputs.append(sourceOut);
