Struct probability::source::Default

pub struct Default(_);

An instance of the default source.

The default source is the Xorshift128+ algorithm.

Implementations

impl Default

pub fn new() -> Default

Create an instance of the default source.

Each thread has its own copy of the default source, and each copy is initialized with the same default seed. Therefore, the usage is thread safe; however, each thread is responsible for reseeding its source.

pub fn seed(self, seed: [u64; 2]) -> Default

Seed the source.

At least one bit of the seed should be nonzero.

Trait Implementations

impl Clone for Default

pub fn clone(&self) -> Default

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Source for Default

pub fn read_u64(&mut self) -> u64

Read u64 uniformly distributed over {0, 1, …, u64::MAX}.

pub fn read_f64(&mut self) -> f64

Read f64 uniformly distributed over [0, 1].

pub fn read<V>(&mut self) -> V where
    V: Value, 

Read a random value.

pub fn iter<V>(&'l mut self) -> Sequence<'l, Self, V> where
    V: Value, 

Read a sequence of random values.
