Struct rand::distributions::Slice

source · [−]
pub struct Slice<'a, T> { /* private fields */ }
Expand description

A distribution to sample items uniformly from a slice.

-

Slice::new constructs a distribution referencing a slice and uniformly -samples references from the items in the slice. It may do extra work up -front to make sampling of multiple values faster; if only one sample from -the slice is required, SliceRandom::choose can be more efficient.

-

Steps are taken to avoid bias which might be present in naive -implementations; for example slice[rng.gen() % slice.len()] samples from -the slice, but may be more likely to select numbers in the low range than -other values.

-

This distribution samples with replacement; each sample is independent. -Sampling without replacement requires state to be retained, and therefore -cannot be handled by a distribution; you should instead consider methods -on SliceRandom, such as SliceRandom::choose_multiple.

-

Example

-
use rand::Rng;
-use rand::distributions::Slice;
-
-let vowels = ['a', 'e', 'i', 'o', 'u'];
-let vowels_dist = Slice::new(&vowels).unwrap();
-let rng = rand::thread_rng();
-
-// build a string of 10 vowels
-let vowel_string: String = rng
-    .sample_iter(&vowels_dist)
-    .take(10)
-    .collect();
-
-println!("{}", vowel_string);
-assert_eq!(vowel_string.len(), 10);
-assert!(vowel_string.chars().all(|c| vowels.contains(&c)));
-

For a single sample, SliceRandom::choose -may be preferred:

- -
use rand::seq::SliceRandom;
-
-let vowels = ['a', 'e', 'i', 'o', 'u'];
-let mut rng = rand::thread_rng();
-
-println!("{}", vowels.choose(&mut rng).unwrap())
-
