Struct servo_rand::ServoRng

pub struct ServoRng {
    pub(crate) rng: ReseedingRng<IsaacCore, ServoReseeder>,
}

Fields

rng: ReseedingRng<IsaacCore, ServoReseeder>

Implementations

impl ServoRng

pub fn new_manually_reseeded(seed: u64) -> ServoRng

Create a manually-reseeding instance of ServoRng.

Note that this RNG does not reseed itself, so care is needed to reseed the RNG is required to be cryptographically sound.

Trait Implementations

impl Default for ServoRng

fn default() -> Self

Create an auto-reseeding instance of ServoRng.

This uses the shared OsRng, so avoids consuming a file descriptor.

impl RngCore for ServoRng

fn next_u32(&mut self) -> u32

Return the next random u32.

fn next_u64(&mut self) -> u64

Return the next random u64.

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

Fill dest with random data.

fn try_fill_bytes(&mut self, bytes: &mut [u8]) -> Result<(), Error>

Fill dest entirely with random data.

impl SeedableRng for ServoRng

type Seed = Seed

Seed type, which is restricted to types mutably-dereferenceable as u8 arrays (we recommend [u8; N] for some N).

fn from_seed(seed: Seed) -> ServoRng

Create a new PRNG using the given seed.

fn seed_from_u64(state: u64) -> Self

Create a new PRNG using a u64 seed.

fn from_rng<R>(rng: R) -> Result<Self, Error>where R: RngCore,

Create a new PRNG seeded from another Rng.

fn from_entropy() -> Self

Creates a new instance of the RNG seeded via getrandom.
