Struct EvaluationState

pub struct EvaluationState<'inst> {
    pub result: Option<i32>,
    /* private fields */
}

The complete machine state of a histogram builder during execution. Each state serves as a continuation of the machine, and may be used to resume execution. The machine is suspended after every range or die roll, which only occur inside RollRange, RollStandardDice, and RollCustomDice instructions.

Fields

result: Option<i32>

The final result of the dice expression, if it has been computed.
