Enhanced slice random operations for scientific computing

Required Methods

fn scientific_shuffle<R: Rng>(&mut self, rng: &mut Random<R>)

Shuffle the slice in place with enhanced performance

fn scientific_choose<R: Rng>(&self, rng: &mut Random<R>) -> Option<&T>

Choose a random element with guaranteed uniform distribution

fn scientific_choose_multiple<R: Rng>( &self, rng: &mut Random<R>, amount: usize, ) -> Vec<&T>

Choose multiple elements without replacement using optimal algorithms

fn scientific_sample_with_replacement<R: Rng>( &self, rng: &mut Random<R>, amount: usize, ) -> Vec<&T>

Sample with replacement

fn scientific_weighted_sample<R: Rng, W>( &self, rng: &mut Random<R>, weights: &[W], amount: usize, ) -> Result<Vec<&T>, String>

where W: Into<f64> + Copy,

Weighted sampling (requires weights)

fn scientific_reservoir_sample<R: Rng>( &self, rng: &mut Random<R>, k: usize, ) -> Vec<&T>

Reservoir sampling for streaming data

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
