Struct rocket::mtls::oid::asn1_rs::nom::lib::std::hash::RandomState

1.7.0 · source ·
pub struct RandomState { /* private fields */ }
Available on crate feature mtls only.
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);

Implementations§
