Struct futures_ringbuf::Dictator

pub struct Dictator { /* fields omitted */ }

Dictator that makes random decisions based on a seed. That is the decisions are reproducible. For reproducible decisions, your use of the dictator must be deterministic.

impl Dictator

pub fn new(seed: u64) -> Self

pub fn please(&mut self, question: &str, prob: f64) -> bool

Ask the dictator permission to do something.

pub fn pick<Idx: SampleUniform + Debug + Copy + PartialOrd>(
    &mut self,
    what: &str,
    range: Range<Idx>
) -> Idx

Ask the dictator to pick from a range of values.

pub fn seed() -> u64

Create a new random seed from entropy.
