Struct schnorr_fun::nonce::GlobalRng

pub struct GlobalRng<R> { /* fields omitted */ }

A zero sized type that wraps an instance of an RNG that implementes Default e.g. OsRng. GlobalRng implements NonceRng and care has been taken to ensure it is Sync.

Examples

use rand::rngs::ThreadRng;
use secp256kfun::nonce::{GlobalRng, NonceRng};
let nonce_rng = GlobalRng::<ThreadRng>::default();
let mut bytes = [0u8; 32];
nonce_rng.fill_bytes(&mut bytes);
assert_ne!(bytes, [0u8; 32]);

fn is_sync<S: Sync>(x: S) -> bool {
    true
}
assert!(is_sync(nonce_rng));

Trait Implementations

impl<R> Clone for GlobalRng<R> where
    R: Clone, 

fn clone(&self) -> GlobalRng<R>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<R> Debug for GlobalRng<R> where
    R: Debug, 

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<R> Default for GlobalRng<R> where
    R: Default, 

fn default() -> GlobalRng<R>

Returns the "default value" for a type.

impl<R> NonceRng for GlobalRng<R> where
    R: Default + RngCore + CryptoRng, 

We implement NonceRng only for rngs we can conjure out of thin air with Default.

fn fill_bytes(&self, bytes: &mut [u8])

Fill bytes with random data.
