Struct tor_llcrypto::util::rand_compat::RngWrapper

source · [−]

pub struct RngWrapper<T>(_);

Expand description

A new-style Rng, wrapped for backward compatibility.

This object implements both the current (0.6.2) version of RngCore, as well as the version from 0.5.1 that the dalek-crypto functions expect.

To get an RngWrapper, use the RngCompatExt extension trait:

use tor_llcrypto::util::rand_compat::RngCompatExt;

let mut wrapped_rng = rand::thread_rng().rng_compat();
