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

pub struct RandomState {
    // some fields omitted
}

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

fn main() { 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); }
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);

Methods

impl RandomState
[src]

fn new() -> RandomState

Constructs a new RandomState that is initialized with random keys.

Examples

fn main() { use std::collections::hash_map::RandomState; let s = RandomState::new(); }
use std::collections::hash_map::RandomState;

let s = RandomState::new();
