Enum Distribution 

pub enum Distribution {
    Uniform {
        low: f64,
        high: f64,
    },
    LogUniform {
        low: f64,
        high: f64,
    },
    IntUniform {
        low: i64,
        high: i64,
    },
    Categorical {
        choices: Vec<String>,
    },
}

The search-space shape recorded for a single suggested parameter.

In the define-by-run model a Distribution is produced by each trial.suggest_* call and handed to the active crate::Sampler, which returns a matching crate::Value. The distribution is also recorded on the crate::Trial so later phases (pruning, adaptive sampling, storage, importance analysis) can reconstruct exactly what was searched.

Variants

Uniform

Continuous uniform over [low, high].

Fields

low: f64

high: f64

LogUniform

Log-uniform over [low, high] (both must be > 0). Sampling is uniform in log-space — appropriate for scale parameters like learning rates.

Fields

low: f64

high: f64

IntUniform

Integer uniform over the inclusive range [low, high].

Fields

low: i64

high: i64

Categorical

Categorical over a fixed set of string labels.

Fields

choices: Vec<String>

Implementations
