Enum regex::backtrack::Job

enum Job {
    Inst {
        ip: usize,
        at: InputAt,
    },
    SaveRestore {
        slot: usize,
        old_pos: Option<usize>,
    },
}

A job is an explicit unit of stack space in the backtracking engine.

The "normal" representation is a single state transition, which corresponds to an NFA state and a character in the input. However, the backtracking engine must keep track of old capture group values. We use the explicit stack to do it.
