Enum HeuristicFallback 

pub enum HeuristicFallback {
    UseHeuristic,
    EmptyOnFail,
    Propagate,
}

What LlmNer::extract should do when the LLM call fails.

Variants

UseHeuristic

On LLM error / timeout / disabled, fall through to the existing extract_tokens heuristic. Recommended default: keeps Stage 1 answering even if the LLM provider is degraded.

EmptyOnFail

Return an empty TokenSet on failure (strict mode — useful when an empty result is preferred over a heuristic guess, e.g. for compliance audits).

Propagate

Bubble the error up to the caller (caller-handles mode).

Trait Implementations

impl Clone for HeuristicFallback

fn clone(&self) -> HeuristicFallback

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HeuristicFallback

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

Formats the value using the given formatter.

impl PartialEq for HeuristicFallback

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