Struct FixedLambdaCheckpoint 

pub struct FixedLambdaCheckpoint { /* private fields */ }

Owned, serde-safe coefficient checkpoint for a fixed-lambda Newton solve.

Coefficients are row-major with shape (rows, cols), where rows are the per-output coefficient count and columns are active outputs/classes. The values deliberately remain private so diagnostics cannot accidentally dump a potentially large coefficient vector; resume code accesses them through Self::values after calling Self::validate.

Implementations

impl FixedLambdaCheckpoint

pub fn new( stage: FixedLambdaSolverStage, coefficients_row_major: Vec<f64>, rows: usize, cols: usize, completed_iterations: usize, ) -> Result<Self, String>

pub fn validate(&self) -> Result<(), String>

Validate persisted checkpoint geometry and coefficient finiteness before rebuilding an ndarray view in a resumed solver.

pub fn stage(&self) -> FixedLambdaSolverStage

pub fn values(&self) -> &[f64]

pub fn rows(&self) -> usize

pub fn cols(&self) -> usize

pub fn completed_iterations(&self) -> usize
