Connection

One connection, in the builder's own shape. It says which output of which block it leaves from, and which block it arrives at.

  • The block the connection leaves from

  • The block the connection arrives at

  • Which of the source block's outputs this connection leaves from, exactly as the block definition's outputs report it — some ids carry a $ prefix and some do not, and the two are not interchangeable.

  • The key this connection is stored under, repeated inside it.
