Enum StabilityClass 

pub enum StabilityClass {
    ExponentialDivergence,
    MarginalDivergence,
    NeutralStability,
    ExponentialConvergence,
    InsufficientData,
}

Stability classification from the Lyapunov exponent.

Maps λ onto qualitative stability regimes that inform grammar state assignment and operator advisory output.

Variants

ExponentialDivergence

λ > λ_crit (default 0.01): exponential divergence. Corroborates Boundary[SustainedOutwardDrift] grammar state.

MarginalDivergence

0 < λ ≤ λ_crit: marginal divergence. Supports Boundary approach — structural monitoring warranted.

NeutralStability

−ε < λ < ε: neutral stability (stationary residual). Corroborates Admissible grammar state.

ExponentialConvergence

λ < −ε: exponential convergence toward nominal. Strongly corroborates Admissible.

InsufficientData

Insufficient data to compute λ (window not full).

Implementations

impl StabilityClass

pub fn from_lambda(lambda: f32) -> Self

Classify from a raw λ value.

pub fn is_diverging(&self) -> bool

Returns true if the trajectory is diverging (λ > ε).

Trait Implementations

impl Clone for StabilityClass

fn clone(&self) -> StabilityClass

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StabilityClass

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

Formats the value using the given formatter.

impl PartialEq for StabilityClass

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