pub trait RandSource<T> {
// Required method
fn rand(&self) -> T;
}Expand description
A trait for random sources that return a random byte integers.
This abstraction allows you to plug in a real random source or a mocked random source in tests.
The random type T is generic (typically u64 or u128)
§Example
use ferroid::RandSource;
struct FixedRand;
impl RandSource<u64> for FixedRand {
fn rand(&self) -> u64 {
1234
}
}
let rng = FixedRand;
assert_eq!(rng.rand(), 1234);
