Struct nom::lib::std::collections::hash_map::RandomState

pub struct RandomState { /* 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

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);

Implementations

impl RandomState

pub fn new() -> RandomState

Constructs a new RandomState that is initialized with random keys.

Examples

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

let s = RandomState::new();
