Struct Mark 

pub struct Mark(/* private fields */);

A saved position, taken by Cursor::save and given back to Cursor::restore.

Opaque on purpose. A position is only meaningful for the cursor that produced it, and an arbitrary index into the token stream is not something the parser should be able to invent.
