Struct rdrand::RdSeed

pub struct RdSeed(_);

A random number generator suited to seed other pseudo-random generators.

This instruction currently is only available in Intel Broadwell processors.

Note: The implementation has not been tested due to the lack of hardware supporting the feature

Methods

impl RdSeed

fn new() -> Result<RdSeed, Error>

fn next_u16(&self) -> u16

Generate a u16 value.

Trait Implementations

impl Clone for RdSeed

fn clone(&self) -> RdSeed

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Rng for RdSeed

fn next_u32(&mut self) -> u32

Return the next random u32.

fn next_u64(&mut self) -> u64

Return the next random u64.

fn next_f32(&mut self) -> f32

Return the next random f32 selected from the half-open interval [0, 1).

fn next_f64(&mut self) -> f64

Return the next random f64 selected from the half-open interval [0, 1).

fn fill_bytes(&mut self, dest: &mut [u8])

fn gen<T>(&mut self) -> T where T: Rand

Return a random value of a Rand type.

fn gen_iter<T>(&'a mut self) -> Generator<'a, T, Self> where T: Rand

Return an iterator that will yield an infinite number of randomly generated items.

fn gen_range<T>(&mut self, low: T, high: T) -> T where T: SampleRange + PartialOrd<T>

fn choose<T>(&mut self, values: &'a [T]) -> Option<&'a T>

Return a random element from values.

fn shuffle<T>(&mut self, values: &mut [T])

Shuffle a mutable slice in place.
