Struct OuterGradientFdComponent 

pub struct OuterGradientFdComponent {
    pub block: String,
    pub index: usize,
    pub analytic: f64,
    pub fd: f64,
}

Per-θ component of an outer-gradient finite-difference audit.

Fields

block: String

Human label for the block this coordinate belongs to (e.g. “timewiggle”).

index: usize

Flat θ index.

analytic: f64

Analytic ∂V/∂θ_i returned by the family evaluator.

fd: f64

Central finite-difference of the outer criterion in θ_i.

Implementations

impl OuterGradientFdComponent

pub fn abs_gap(&self) -> f64

Absolute analytic−FD gap.

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

analytic/fd ratio (None when fd≈0). A clean −1 signals a sign convention; a stable constant ≠1 signals a dropped/extra additive term.

Trait Implementations

impl Clone for OuterGradientFdComponent

fn clone(&self) -> OuterGradientFdComponent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OuterGradientFdComponent

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

Formats the value using the given formatter.
