Struct std::rand::reseeding::ReseedingRng [−] [src]

pub struct ReseedingRng<R, Rsdr> {
    rng: R,
    generation_threshold: usize,
    bytes_generated: usize,
    pub reseeder: Rsdr,
}
Unstable (rand)

: use rand from crates.io

A wrapper around any RNG which reseeds the underlying RNG after it has generated a certain number of random bytes.

Fields

rng
Unstable (rand)

: use rand from crates.io

generation_threshold
Unstable (rand)

: use rand from crates.io

bytes_generated
Unstable (rand)

: use rand from crates.io

reseeder
Unstable (rand)

: use rand from crates.io

Controls the behaviour when reseeding the RNG.

Methods

impl<R, Rsdr> ReseedingRng<R, Rsdr> where R: Rng, Rsdr: Reseeder<R>

fn new(rng: R, generation_threshold: usize, reseeder: Rsdr) -> ReseedingRng<R, Rsdr>

Unstable (rand)

: use rand from crates.io

Create a new ReseedingRng with the given parameters.

Arguments

  • rng: the random number generator to use.
  • generation_threshold: the number of bytes of entropy at which to reseed the RNG.
  • reseeder: the reseeding object to use.

fn reseed_if_necessary(&mut self)

Unstable (rand)

: use rand from crates.io

Reseed the internal RNG if the number of bytes that have been generated exceed the threshold.
