Struct RandGen

pub struct RandGen { /* private fields */ }

Random number generator based on xoroshiro128. Requires two internal state variables. You may prefer SplitMix64 or Rng which only use one u64 as state.

Implementations

impl RandGen

pub fn new() -> Self

pub fn next(&mut self) -> u64

Next random unsigned 64bit integer.

pub fn next_open01(&mut self) -> f64

Next random float between [0.0, 1.0).

Trait Implementations

impl Clone for RandGen

fn clone(&self) -> RandGen

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RandGen

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for RandGen

fn eq(&self, other: &RandGen) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
