Struct Pcg32

pub struct Pcg32 { /* private fields */ }

A PCG32 random number generator.

Implementations

impl Pcg32

pub const fn new(initstate: u64, initseq: u64) -> Self

Initializes a PCG32 generator with two u64 seeds.

The arguments specify the starting state and the output sequence, respectively, for the constructed generator. You can pass any 64-bit value to each argument, though the most significant bit of initseq is ignored. See the pcg32_srandom_r documentation of the official library for further details.

pub fn generate(&mut self) -> u32

Generates a pseudorandom uniformly distributed 32-bit unsigned integer.

Trait Implementations

impl Clone for Pcg32

fn clone(&self) -> Pcg32

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Pcg32

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

Formats the value using the given formatter.

impl Default for Pcg32

fn default() -> Self

Returns the “default value” for a type.

impl Hash for Pcg32

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Pcg32

fn eq(&self, other: &Pcg32) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
