Struct std::collections::hash_map::RandomState
1.7.0 · source · pub struct RandomState { /* private fields */ }
Expand description
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::hash::RandomState;
let s = RandomState::new();
let mut map = HashMap::with_hasher(s);
map.insert(1, 2);
