Struct reservoir_sampler::Reservoir[][src]

pub struct Reservoir<T> { /* fields omitted */ }
Expand description

A Reservoir is a just a pool, but for random number generation, total items’ count passed through is known.

Implementations

impl<T: Clone> Reservoir<T>[src]

pub fn with_capacity(n: usize) -> Self[src]

Trait Implementations

impl<T> ReservoirSampler for Reservoir<T>[src]

type Item = T

Each sampler only processes the same type of items.

fn sample(&mut self, it: Self::Item) -> (usize, usize, Option<Self::Item>)[src]

A sampler processes exactly one item each time, for the items come in as a stream. Read more

fn samples(&self) -> &[Option<Self::Item>][src]

A reservoir should know which items are held no matter if the sampling process is finished. Read more

fn lock(self) -> Vec<Option<Self::Item>>[src]

End the sampling process. Shuffling the order of the result is allowed.
