Struct ProjectedRow 

pub struct ProjectedRow { /* private fields */ }

A projected row whose slots still reference the preceding JOIN edge.

The outer side may itself be projected, so a long selective JOIN chain is represented as a shallow sequence of slot maps instead of repeatedly copying every retained payload value into a new Row at each edge.
