Struct ConstantRandomnessSource

pub struct ConstantRandomnessSource<ANumber: Number> { /* private fields */ }

A trivial RandomnessSource that always returns the same sequence of values based on a seed. Which by default is constant as well.

Warning

This struct should only be used for testing purposes, not in production.

Implementations

impl<ANumber: Number> ConstantRandomnessSource<ANumber>

pub fn new(seed: ANumber) -> Self

Creates a new ConstantRandomnessSource with the given seed.

Trait Implementations

impl<ANumber: Clone + Number> Clone for ConstantRandomnessSource<ANumber>

fn clone(&self) -> ConstantRandomnessSource<ANumber>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<ANumber: Debug + Number> Debug for ConstantRandomnessSource<ANumber>

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

Formats the value using the given formatter.

impl<ANumber: Number> Default for ConstantRandomnessSource<ANumber>

fn default() -> Self

Returns the “default value” for a type.

impl<ANumber: PartialEq + Number> PartialEq for ConstantRandomnessSource<ANumber>

fn eq(&self, other: &ConstantRandomnessSource<ANumber>) -> 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.

impl<ANumber: Number> RandomnessSource for ConstantRandomnessSource<ANumber>

type TNumber = ANumber

fn next_number(&mut self) -> Self::TNumber

Returns the next random number.

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

Fills the given mut slice with random bytes.
