Struct FitController 

pub struct FitController<E: Equation + Send + 'static> { /* private fields */ }

A running fit that you advance one cycle at a time.

It’s ready to go as soon as it’s built, so the first step runs cycle 1. The accessors read the current state between steps, and finish or into_result turn it into a result.

Implementations

impl<E: Equation + Send + 'static> FitController<E>

pub fn step(&mut self) -> Result<Status>

Run one cycle and return the new Status.

Continue means there’s more to do; Stop means the algorithm is finished and further steps won’t change the outcome.

pub fn request_stop(&mut self)

Flag the fit as Aborted so the result shows an early stop.

This only sets the status; it won’t halt a later step, which runs a full cycle and overwrites it. Call it just before into_result.

pub fn cycle(&self) -> usize

The current cycle number (0 before the first step).

pub fn status(&self) -> &Status

The current Status of the fit.

pub fn theta(&self) -> &Theta

The current support points and weights.

pub fn psi(&self) -> &Psi

The current likelihood matrix.

pub fn likelihood(&self) -> f64

The current log-likelihood.

pub fn n2ll(&self) -> f64

The current negative two log-likelihood (objective function).

pub fn error_models(&self) -> &AssayErrorModels

The current error models (updated when the algorithm optimizes them).

pub fn finish(self) -> Result<NonParametricResult<E>>

Run the fit to completion and return the result.

Safe to call anytime: if the fit has already stopped, it just returns the result.

pub fn into_result(self) -> Result<NonParametricResult<E>>

Turn the current state into a result as-is, without running more cycles.
