Struct CalibrationSession 

pub struct CalibrationSession {
    pub config: SessionConfig,
    pub samples: Vec<SampleRecord>,
    pub precision_history: Vec<PrecisionRecord>,
    pub iteration: usize,
    /* private fields */
}

An active calibration session tracking model, samples, and history.

Fields

config: SessionConfig

Session configuration.

samples: Vec<SampleRecord>

All measurements collected so far.

precision_history: Vec<PrecisionRecord>

Precision snapshots from each completed iteration.

iteration: usize

Current iteration count (0-based).

Implementations

impl CalibrationSession

pub fn new( config: SessionConfig, feature_fn: impl Fn(f64) -> Vec<f64> + 'static, feature_dim: usize, ) -> Self

Create a new calibration session.

Arguments

• config: session configuration
• feature_fn: maps scalar input → feature vector (must have length feature_dim)
• feature_dim: number of features D

pub fn add_measurement(&mut self, raw_input: f64, measured_output: f64)

Add a new measurement from the user/sensor.

pub fn add_measurements(&mut self, inputs: &[f64], outputs: &[f64])

Add multiple measurements at once.

pub fn sample_count(&self) -> usize

Number of samples currently in the session.

pub fn next_iteration(&mut self) -> IterationOutcome

Run one iteration of the calibration state machine.

Returns an IterationOutcome indicating what to do next. The caller should add new measurements (at the recommended locations) before calling this again.

pub fn export_history_json(&self) -> String

Export the calibration history as a JSON string.
