pub struct RandomState { /* private fields */ }

Expand description

A particular instance RandomState will create the same instances ofHasher, but the hashers created by two different RandomStateinstances are unlikely to produce the same result for the same values.

§Examples

use std::collections::HashMap;
use std::hash::RandomState;

let s = RandomState::new();
let mut map = HashMap::with_hasher(s);
map.insert(1, 2);
