Struct ModelHealthReport 

pub struct ModelHealthReport { /* private fields */ }

Snapshot of model parameter health.

Computed from a flat slice of weights and an optional intercept. Detects NaN / Infinity contamination and reports basic weight statistics. Does not store the parameters themselves.

Examples

use rill_ml::diagnostics::ModelHealthReport;

let report = ModelHealthReport::from_parameters(&[0.1, -0.2, 0.5], Some(1.0));
assert_eq!(report.parameter_count(), 4);
assert!(report.is_healthy());
assert_eq!(report.weight_range(), Some(1.2));

Implementations

impl ModelHealthReport

pub fn from_parameters(weights: &[f64], intercept: Option<f64>) -> Self

Build a report by scanning a slice of weights plus an optional intercept.

parameter_count = weights.len() + intercept.is_some() as usize. state_size_bytes = parameter_count * 8 (one f64 per parameter).

Empty input yields weight_min == weight_max == None and a healthy report (no NaN / Infinity detected).

pub const fn parameter_count(&self) -> usize

Total number of parameters (weights plus optional intercept).

pub const fn weight_min(&self) -> Option<f64>

Minimum weight value, or None if no parameters were supplied.

pub const fn weight_max(&self) -> Option<f64>

Maximum weight value, or None if no parameters were supplied.

pub const fn has_nan(&self) -> bool

Whether any parameter is NaN.

pub const fn has_infinity(&self) -> bool

Whether any parameter is positive or negative Infinity.

pub const fn state_size_bytes(&self) -> usize

Estimated state size in bytes (parameter_count * 8).

pub fn is_healthy(&self) -> bool

Whether the parameters are free of NaN and Infinity.

pub fn weight_range(&self) -> Option<f64>

Spread of weights (weight_max - weight_min), or None if no data.
