Struct ARng

Source 
pub struct ARng(/* private fields */);
Expand description

A very simple, seedable atomic random number generator based on sin().

Implementations§

Source§

impl ARng

Source

pub fn new(seed: usize) -> ARng

Creates a new instance with given seed.

Source

pub fn get(&self) -> f64

Returns a random number between 0.0 and non-inclusive 1.0

Source

pub fn range(&self, min: f64, max: f64) -> f64

Returns a random number between min and non-inclusive max.

Source

pub fn chose<'a, T>(&self, source: &'a [T]) -> &'a T

Returns a random item from given slice.
