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.
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);
impl RandomState[src]
pub fn new() -> RandomState[src]
Constructs a new RandomState that is initialized with random keys.
