Implementations

impl FroggyRand

pub fn new(seed: u64) -> Self

pub fn from_hash<T: Hash>(x: T) -> Self

pub fn subrand<T: Hash>(&self, x: T) -> Self

pub fn gen<T: Hash>(&self, x: T) -> u64

Should be uniform over all u64 values

pub fn gen_unit<T: Hash>(&self, x: T) -> f32

Should be uniform in [0, 1]

pub fn gen_range<T: Hash>(&self, x: T, min: f32, max: f32) -> f32

Should be uniform in [min, max]

pub fn choose<'a, T: Hash, X>(&self, x: T, choices: &'a [X]) -> &'a X

Should give a uniform random element of the slice choices.

pub fn gen_froggy<T: Hash>(&self, x: T, min: f32, max: f32, n: u32) -> f32

I dont know what a statistic is Approx normal dist https://en.wikipedia.org/wiki/Irwin%E2%80%93Hall_distribution

pub fn gen_usize_range<T: Hash>(&self, x: T, min: usize, max: usize) -> usize

pub fn shuffle<T: Hash, X>(&self, x: T, xs: &mut [X])

pub fn gen_byte<T: Hash>(&self, x: T) -> u8

Should be uniform in [0, 255]

pub fn gen_perf(&self, seed: i32) -> u64

More performant gen() if the only control parameter you need is a single int.

pub fn gen_unit_perf(&self, seed: i32) -> f32

More performant gen_unit() if the only control parameter you need is a single int.
