Struct streaming_algorithms::SampleUnstable

pub struct SampleUnstable<T> { /* fields omitted */ }

Reservoir sampling. Without replacement, and the returned order is unstable.

Methods

impl<T> SampleUnstable<T>

pub fn new(samples: usize) -> Self

Create a SampleUnstable that will provide a sample of size samples.

pub fn push<R: Rng>(&mut self, t: T, rng: &mut R)

"Visit" this element
