Struct GridSampler 

pub struct GridSampler { /* private fields */ }

Exhaustive grid search over all combinations.

Uses lazy index-based generation: instead of building the full cartesian product in memory, it computes the parameter set for a given trial index on the fly. Safe for large search spaces.

Implementations

impl GridSampler

pub fn new(points_per_dim: usize) -> Self

Trait Implementations

impl Sampler for GridSampler

fn sample( &mut self, space: &SearchSpace, trial_index: usize, ) -> Result<Option<HashMap<String, Value>>>

Sample the next set of parameters. Returns None when exhausted.

fn n_trials(&self) -> Option<usize>

Total number of trials this sampler will produce (if known).
