Struct RngSeed 

pub struct RngSeed(/* private fields */);

A seed for a runtime’s random choices: where a task spawned from outside its workers goes, and which branch of a fair select! is polled first.

A runtime built with Builder::rng_seed seeds each of its workers, and each thread in its block_on, from the seed: run after run, such a thread draws the same numbers, so its choices repeat as long as what it chooses among is the same. The threads still interleave as the system runs them.

use nuclei::runtime::{RngSeed, Runtime};

let seed = RngSeed::from_bytes(b"a run to repeat");
assert_eq!(seed, RngSeed::from_bytes(b"a run to repeat"));
let rt = Runtime::builder().rng_seed(seed).build().unwrap();

Implementations

impl RngSeed

pub fn new() -> Self

A seed different each time.

pub fn from_bytes(bytes: &[u8]) -> Self
