Struct futures_ringbuf::Dictator

pub struct Dictator { /* private fields */ }

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.

Implementations

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(&self) -> u64

Return the seed used when creating this Dictator.

pub fn new_seed() -> u64

Create a new random seed from entropy.
