Enum EvalScope 

pub enum EvalScope {
    OuterDerivative,
    InnerCoefficient,
}

Scope of an outer-evaluation context — distinguishes a real outer derivative evaluation (where auto-subsample is allowed to install a fresh stratified mask and emit phase prints) from an inner coefficient line-search trial (where the family must reuse the outer row measure, so auto-subsample must stay disabled).

Variants

OuterDerivative

Real outer derivative evaluation: ρ has advanced; auto-subsample install paths may build/refresh a mask keyed on this ρ.

InnerCoefficient

Inner coefficient trial (joint-Newton / line-search) at fixed outer ρ: row measure must remain identical to the surrounding outer eval, so auto-subsample must not install a fresh mask.

Trait Implementations

impl Clone for EvalScope

fn clone(&self) -> EvalScope

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for EvalScope

impl Debug for EvalScope

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

Formats the value using the given formatter.

impl Eq for EvalScope

impl PartialEq for EvalScope

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