Struct SurvivalTimeColumns 

pub struct SurvivalTimeColumns {
    pub entry_col: Option<usize>,
    pub exit_col: usize,
}

Resolved survival entry/exit column indices for a saved survival model.

entry_col is None when the model was trained with the right-censored shorthand Surv(time, event); callers synthesize a zero entry time per row in that case via SurvivalTimeColumns::row_entry_time. Mirrors the CLI predict path so every site that consumes saved survival metadata applies the same fallback contract.

Fields

entry_col: Option<usize>

exit_col: usize

Implementations

impl SurvivalTimeColumns

pub fn row_entry_time(&self, data: ArrayView2<'_, f64>, i: usize) -> f64

Entry time for row i, defaulting to 0.0 when the saved model has no survival_entry column (right-censored shorthand).
