Struct DrsMark 

pub struct DrsMark { /* private fields */ }

A point in the DRS’s growth: the box the parse was in, and how many referents each box then held. A parse that backtracks rewinds to it, so a referent registered on an abandoned path does not outlive the path — no pronoun finds it, and no conditional quantifies over it.
