Struct janetrs::JanetRng

pub struct JanetRng { /* private fields */ }

Type representing the Janet pseudorandom number generator

It uses xorwow variation of Xorshift random number generator, but the algorithm used is not set to stone and can be changed in future versions of Janet.

Trait Implementations

impl Clone for JanetRng

fn clone(&self) -> JanetRng

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for JanetRng

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<JanetRng> for Janet

fn from(value: JanetRng) -> Self

Converts to this type from the input type.

impl From<JanetRng> for JanetAbstract

fn from(value: JanetRng) -> Self

Converts to this type from the input type.

impl IsJanetAbstract for JanetRng

type Get = JanetRng

The type that you get when you call JanetAbstract::get family of functions.

const SIZE: usize = 20usize

The size of the type that is being transformed as JanetAbstract.

fn type_info() -> &'static JanetAbstractType

Returns the table of the name of the Self and all possible polymorphic function pointer that a Abstract type can have in Janet.

impl JanetTypeName for JanetRng

fn name() -> String

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

Fill dest entirely with random data.

impl SeedableRng for JanetRng

type Seed = Vec<u8>

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

fn from_seed(seed: Self::Seed) -> Self

Create a new PRNG using the given seed.

fn seed_from_u64(state: u64) -> Self
