The commands iterator did a toposort on the whole Hugr, ignoring the hierarchy.
This generated problems with #370, since circuits may now be nested somewhere in the hugr.
It would also have caused problems with circuit boxes, but we don't support that yet here.
We use a
SiblingGraph
now, to ensure that we only explore the top-level region of the circuit.Subcircuits will be returned as a single command.
Adds a
build_module_with_circuit
helper to build circuits inside modules.Closes #42.
