Struct rand::reseeding::ReseedingRng

pub struct ReseedingRng<R, Rsdr> {
    pub reseeder: Rsdr,
    // some fields omitted
}

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

Fields

reseeder

Controls the behaviour when reseeding the RNG.

Methods

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

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

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)

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