std::collections::hash_map::RandomState
Struct 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);
Methods
impl RandomState
[src]
fn new() -> RandomState
Constructs a new RandomState that is initialized with random keys.
Examples
use std::collections::hash_map::RandomState; let s = RandomState::new();
