to_igraph

to_igraph(
    graph,
    directed=True,
    hyperedge_mode="skip",
    slice=None,
    slices=None,
    public_only=False,
    reify_prefix="he::",
)

Export AnnNet → (igraph.AnnNet, manifest).

hyperedge_mode: {"skip","expand","reify"} - "skip": drop HE edges from igG (manifest keeps them) - "expand": cartesian product (directed) / clique (undirected) - "reify": add a node per HE and membership edges V↔HE carrying roles/coeffs

from_igraph

from_igraph(
    igG,
    manifest,
    *,
    hyperedge="none",
    he_node_flag="is_hyperedge",
    he_id_attr="eid",
    reify_prefix="he::"
)

Reconstruct a AnnNet from igraph.AnnNet + manifest.

hyperedge: "none" (default) | "reified" When "reified", also detect hyperedge nodes in igG and rebuild true hyperedges that are NOT present in the manifest.
