Struct secp256kfun::nonce::GlobalRng

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

A zero sized type that wraps an RNG that implementes Default e.g. ThreadRng. 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> Clone for GlobalRng<R>

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> Debug for GlobalRng<R>

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

Formats the value using the given formatter.

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

fn default() -> GlobalRng<R>

Returns the “default value” for a type.

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

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.
