Structs

Row

subtree is what the holder pays for this ref; shared marks a row priced net of a tree an earlier row already carried.

Tree

Work

What a stream or a render did, counted exactly and alike on every machine: the samples written, the silence proofs run, the price of the work, and the lines and atoms summed where they are counted.

Functions

dominating

The root restates the whole, so the refusal names the costliest row under it.

total

A closed form’s refs are inlined into its own collapse and are never on the materialize list, so summing that list counts nothing twice.
