The main logic to translate meta code (Rule[Tile]) to proper RUL2 code (Rule[IdTile]). The crux of that is that a single meta rule can result in multiple RUL2 rules, based on the symmetries of the tiles involved. Exactly those rules and orientations will be generated that are necessary. Compare, for example:

scala> transduce( L1Rhw2~WE | (Dirtroad ~> L1Rhw2)~WE )
Rule( 0x57100000,1,0 | 0x57000000,1,0 | 0x57100000,1,0 | 0x57100000,1,0 )

scala> transduce( Mis~WE & Rail~NW | (Dirtroad ~> Mis)~WE & Dirtroad~ES )
Rule( 0x57024580,1,0 | 0x57004A00,3,0 | 0x57024580,1,0 | 0x57024A00,3,0 )

If in doubt, start up the sbt console and use the transduce function to check the output.
