Struct FusionSubgraph 

pub struct FusionSubgraph<'a> {
    pub members: &'a [Box<dyn PolydatNode>],
    pub wiring: &'a [Vec<WireSource>],
    pub out_ports: &'a [(usize, usize)],
}

Borrowed view of the subgraph a fusion node replaced. Local wiring convention: WireSource::Input(i) refers to the fusion node’s i-th input wire in the OUTER graph; NodeOutput(j, p) refers to member j’s port p.

Fields

members: &'a [Box<dyn PolydatNode>]

The original member nodes, verbatim.

wiring: &'a [Vec<WireSource>]

Per-member local wiring (see convention above).

out_ports: &'a [(usize, usize)]

Per fusion output port: (member index, member port) — the original producer behind that port.
