Struct DeterministicRng 

pub struct DeterministicRng { /* private fields */ }

Tiny deterministic RNG used by the simulator.

This is intentionally simple and reproducible across platforms.

Implementations

impl DeterministicRng

pub const fn new(seed: u64) -> Self

Create a new deterministic RNG from a seed.

pub const fn next_u64(&mut self) -> u64

Next pseudo-random u64.

pub const fn next_bounded(&mut self, upper_exclusive: u64) -> u64

Next value in [0, upper_exclusive).

pub fn hit_rate_percent(&mut self, percent: u8) -> bool

Bernoulli trial with integer percent.

Trait Implementations

impl Clone for DeterministicRng

fn clone(&self) -> DeterministicRng

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeterministicRng

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DeterministicRng

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for DeterministicRng

fn eq(&self, other: &DeterministicRng) -> 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 Serialize for DeterministicRng

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
