Struct TrainingState 

pub struct TrainingState {
    pub iterations: Vec<IterationState>,
    pub best_iteration: Option<usize>,
    pub best_validation_loss: Option<f64>,
}

Complete training history and state.

Stores all iteration states and tracks the best performing iteration for early stopping and model selection.

Fields

iterations: Vec<IterationState>

Per-iteration training state history.

best_iteration: Option<usize>

Iteration with the best validation loss (if early stopping is used).

best_validation_loss: Option<f64>

Best validation loss achieved during training.
