Struct SavedSurvivalTimeBasis 

pub struct SavedSurvivalTimeBasis {
    pub basisname: String,
    pub degree: Option<usize>,
    pub knots: Option<Vec<f64>>,
    pub keep_cols: Option<Vec<usize>>,
    pub smooth_lambda: Option<f64>,
    pub anchor: f64,
}

Persistable snapshot of the time-basis state used by a survival fit.

Every survival family routes through SurvivalTimeBuildOutput during the fit, but the FFI save path needs only the metadata — not the full design matrices. This struct is the single source of truth that flows from the workflow-level basis construction, through the family-specific fit result, into the saved-model payload via crate::inference::model::FittedModelPayload::apply_survival_time_basis.

Threading this snapshot end-to-end eliminates the prior bug pattern where each FFI builder had to reconstruct the metadata from fit_config + the formula (silent drift risk; one builder forgetting to do so caused the marginal-slope save→load break).

Fields

basisname: String

degree: Option<usize>

knots: Option<Vec<f64>>

keep_cols: Option<Vec<usize>>

smooth_lambda: Option<f64>

anchor: f64

Implementations

impl SavedSurvivalTimeBasis

pub fn from_build(build: &SurvivalTimeBuildOutput, anchor: f64) -> Self

Build a snapshot from the realised time-basis state and the entry anchor that was used during the fit.

Trait Implementations

impl Clone for SavedSurvivalTimeBasis

fn clone(&self) -> SavedSurvivalTimeBasis

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SavedSurvivalTimeBasis

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

Formats the value using the given formatter.

impl PartialEq for SavedSurvivalTimeBasis

fn eq(&self, other: &SavedSurvivalTimeBasis) -> 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.
