Struct FoldContext 

pub struct FoldContext {
    pub strict: bool,
    pub epsilon: f64,
    pub semiring: FoldSemiring,
}

Per-fold evaluation context threaded into LocyAggState::ingest_indices.

Carries the probability-domain policy (strict), the underflow guard (epsilon, used by bounded-product log-space switching), and the active FoldSemiring. Constructed once per FOLD execution and passed by reference to every per-group ingest call.

Fields

strict: bool

When true, probability-domain aggregates error on inputs outside [0, 1] instead of clamping them with a warning.

epsilon: f64

Underflow threshold: bounded-product switches to log-space once the running product drops below this value. 0.0 disables the switch.

semiring: FoldSemiring

Active probability semiring for this fold.

Trait Implementations

impl Clone for FoldContext

fn clone(&self) -> FoldContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for FoldContext

impl Debug for FoldContext

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

Formats the value using the given formatter.

impl Default for FoldContext

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for FoldContext

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