Struct Random 

pub struct Random { /* private fields */ }

Uniform random sampling within parameter bounds.

At each call, a parameter is chosen uniformly at random, then a value is sampled uniformly from its [min, max] range and quantized to the nearest step (if configured). The sample is rejected if it was already visited. Returns None after MAX_RETRIES consecutive rejections.

rng is wrapped in a Mutex so that Random implements Sync, which is required by VariationGenerator to allow [ExperimentEngine] to be used with tokio::spawn. The mutex is only ever locked from a single thread (the experiment loop is sequential), so there is no contention.

Implementations

impl Random

pub fn new(search_space: SearchSpace, seed: u64) -> Self

Create a new Random generator with a deterministic seed.

Trait Implementations

impl VariationGenerator for Random

fn next( &mut self, _baseline: &ConfigSnapshot, visited: &HashSet<Variation>, ) -> Option<Variation>

Produce the next untested variation, or None if the space is exhausted.

fn name(&self) -> &'static str

Strategy name for logging and metrics.
