Struct HeaderCopy 

pub struct HeaderCopy { /* private fields */ }

Section 26.6’s transformation, at one budget.

The budget is a field rather than a constant because the two levels that run this want different ones, and it comes with the name for the same reason: the two instances are two entries in crate::pass::PASSES and a pipeline picks one by naming it.
