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);
