constraint_crdt::simulation

Struct SimRng 

Source 
pub struct SimRng { /* private fields */ }
Expand description

Simulation seed for deterministic randomness.

Implementations§

Source§

impl SimRng

Source

pub fn new(seed: u64) -> Self

Source

pub fn next_u64(&mut self) -> u64

xorshift64 — fast, deterministic, good enough for simulation.

Source

pub fn next_f64(&mut self) -> f64

Uniform f64 in [0, 1)

Source

pub fn should_drop(&mut self, loss_rate: f64) -> bool

Should we drop this message? (based on loss rate 0.0-1.0)

Source

pub fn random_peer(&mut self, self_idx: usize, total: usize) -> usize

Pick a random peer index (not self).
