Struct tyche::dice::roller::FastRand

source ·
pub struct FastRand(/* private fields */);
Expand description

Generates rolls with random values using [fastrand]. Requires the fastrand feature (enabled by default).

§Examples

§Default fastrand roller

use tyche::dice::{roller::{FastRand as FastRandRoller, Roller}, Dice};

let mut roller = FastRandRoller::default();
let dice = Dice::new(4, 6);
let _ = roller.roll(&dice, true)?;
let _ = roller.roll(&dice, true)?;

§Custom fastrand roller (seeded)

use tyche::dice::{roller::{FastRand as FastRandRoller, Roller}, Dice};
use fastrand::Rng;

let mut roller = FastRandRoller::new(Rng::with_seed(0x750c38d574400));
let dice = Dice::new(4, 6);
let _ = roller.roll(&dice, true)?;
let _ = roller.roll(&dice, true)?;

Implementations§

source§

impl FastRand

source

pub const fn new(rng: Rng) -> Self

Creates a new fastrand roller that uses the given RNG instance to generate rolls.

source

pub fn with_seed(seed: u64) -> Self

Creates a new fastrand roller that uses a pre-seeded RNG instance to generate rolls.
