Module gadgets 

Weighted triangular lattice gadgets with WeightedTri prefix.

This module contains gadget definitions for triangular lattice mapping. All gadgets use weighted mode (weight 2 for standard nodes).

Structs

WeightedTriBranch

Weighted triangular branch gadget - matches Julia’s Branch gadget with weights.

WeightedTriBranchFix

Weighted triangular branch fix gadget.

WeightedTriBranchFixB

Weighted triangular branch fix B gadget.

WeightedTriCross

Weighted triangular cross gadget - matches Julia’s Cross gadget with weights.

WeightedTriEndTurn

Weighted triangular end turn gadget - matches Julia’s EndTurn gadget with weights.

WeightedTriTConDown

Weighted triangular T-connection down gadget.

WeightedTriTConLeft

Weighted triangular T-connection left gadget - matches Julia’s TCon gadget with weights.

WeightedTriTConUp

Weighted triangular T-connection up gadget.

WeightedTriTapeEntry

Tape entry recording a weighted triangular gadget application.

WeightedTriTrivialTurnLeft

Weighted triangular trivial turn left gadget.

WeightedTriTrivialTurnRight

Weighted triangular trivial turn right gadget.

WeightedTriTurn

Weighted triangular turn gadget - matches Julia’s TriTurn gadget.

WeightedTriWTurn

Weighted triangular W-turn gadget - matches Julia’s WTurn gadget with weights.

Enums

SourceCell

Cell type for source matrix pattern matching.

Traits

WeightedTriangularGadget

Trait for weighted triangular lattice gadgets.

Functions

apply_crossing_gadgets

Apply all weighted triangular crossing gadgets to resolve crossings. Returns the tape of applied gadgets.

apply_simplifier_gadgets

Apply simplifier gadgets to the weighted triangular grid. This matches Julia’s apply_simplifier_gadgets! for TriangularWeighted mode.

tape_entry_mis_overhead

Get MIS overhead for a weighted triangular tape entry. For triangular mode, crossing gadgets use their native overhead, but simplifiers (DanglingLeg) use weighted overhead = unweighted * 2. Julia: mis_overhead(w::WeightedGadget) = mis_overhead(w.gadget) * 2
