Struct TrialSummary 

pub struct TrialSummary {
    pub total: usize,
    pub completed: usize,
    pub pruned: usize,
    pub failed: usize,
    pub best_trial_id: Option<String>,
    pub best_value: Option<f64>,
    pub objective: Option<String>,
}

Trial statistics for a study run.

Fields

total: usize

Trials the study ran, in any terminal state.

completed: usize

Trials that ran to completion.

pruned: usize

Trials a pruner stopped early — control flow, not failure.

failed: usize

Trials that ended in an error.

best_trial_id: Option<String>

Id of the best-scoring trial, None when none scored.

best_value: Option<f64>

Objective value of the best trial.

objective: Option<String>

Metric the study optimized, when it declares one.

Trait Implementations

impl Clone for TrialSummary

fn clone(&self) -> TrialSummary

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TrialSummary

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

Formats the value using the given formatter.

impl Default for TrialSummary

fn default() -> TrialSummary

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TrialSummary

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TrialSummary

fn eq(&self, other: &TrialSummary) -> 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 TrialSummary

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
