In pratice, the approach of separate RNGs with different seeds for threads/processes is widely used (even though theoretically those RNGs might have overlaping sequences, which is undesirable). For more discussions on this approach, please refer to The Rust Rand Book - Parallel RNGs and Seed Many RNGs in Rust . The …
Seed Many RNGs in Rust
There are different ways to seed many RNGs (for parallel RNGs).
Below summarizes 3 popular ways.
Seeding RNGs using
std::collections::hash_map::RandomState
or rand::thread_rng
is preferred.
Seed Using System Time
use std::time::{SystemTime, UNIX_EPOCH};
use rand::SmallRng;
fn main () {
let seed = SystemTime::now()
.duration_since(UNIX_EPOCH)
.unwrap()
.as_nanos …

Tips and Traps¶
The command-line tool of some (e.g., network) applications might be slow to authenticate. If you use pexect to automate such a command-line tool, it is best to wait for sometime after sending password using
child.sendline(passwd)
. If the authentication has ouput on both success and failure, a smart way is to wait for the success or failure message to come out.
