Struct Backtrace 

pub struct Backtrace<Term, NonTerm> {
    pub traces: Vec<Vec<ShiftedRule<Term, NonTerm>>>,
}

Backtracing information for parsing context. What current parser was trying to parse, and what rules were applied.

Fields

traces: Vec<Vec<ShiftedRule<Term, NonTerm>>>

0’th element is the current parsing state, and through the backtrace, it goes to the initial state.
