Struct LibcRng 

pub struct LibcRng {}

Non-deterministic random number generator using MEGA65 Libc

Implements the rand::RngCore trait and can thus be used with Rusts rand crate.

Examples

use mos_hardware::mega65::random;
use rand::seq::SliceRandom;
let mut rng = LibcRng::default();
let value = [11, 23].choose(&mut rng).unwrap(); // 11 or 23

Implementations

impl LibcRng

pub fn new(seed: LibcSeed) -> Self

New seeded generator

Trait Implementations

impl Default for LibcRng

fn default() -> LibcRng

Returns the “default value” for a type.

impl RngCore for LibcRng

fn next_u32(&mut self) -> u32

Return the next random u32.

fn next_u64(&mut self) -> u64

Return the next random u64.

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

Fill dest with random data.

fn try_fill_bytes(&mut self, dest: &mut [u8]) -> Result<(), Error>

Fill dest entirely with random data.

impl SeedableRng for LibcRng

type Seed = LibcSeed

Seed type, which is restricted to types mutably-dereferenceable as u8 arrays (we recommend [u8; N] for some N).

fn from_seed(seed: Self::Seed) -> Self

Create a new PRNG using the given seed.

fn seed_from_u64(state: u64) -> Self

Create a new PRNG using a u64 seed.

fn from_rng<R>(rng: R) -> Result<Self, Error>

where R: RngCore,

Create a new PRNG seeded from another Rng.
