Struct std::collections::hash_map::RandomState1.7.0[][src]

pub struct RandomState { /* fields omitted */ }
Expand description

RandomState is the default state for HashMap types.

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

Examples

use std::collections::HashMap;
use std::collections::hash_map::RandomState;

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

Implementations

Constructs a new RandomState that is initialized with random keys.

Examples

use std::collections::hash_map::RandomState;

let s = RandomState::new();
Run
