Struct HeuristicsBank 

pub struct HeuristicsBank { /* private fields */ }

The heuristics bank: a fixed-size collection of typed degradation motifs.

Version 1.0: 12 entries covering the primary distributed Rust system failure patterns. The bank is finite and versioned — novel patterns produce UnclassifiedStructuralAnomaly.

Implementations

impl HeuristicsBank

pub fn default_bank() -> Self

Create a bank with the default Rust distributed-systems entries.

pub fn custom(entries: &'static [HeuristicEntry]) -> Self

Create a bank with custom entries.

pub fn match_sign( &self, sign: &ResidualSign, grammar_state: GrammarState, ) -> MatchResult

Match a residual sign against the bank.

Returns the best-matching heuristic (highest confidence) or UnclassifiedStructuralAnomaly if no entry matches.

Only matches when the grammar state is Boundary or Violation. In Admissible state, returns NoAnomaly.

pub fn match_sign_with_priors( &self, sign: &ResidualSign, grammar_state: GrammarState, priors: &StaticPriorSet, ) -> MatchResult

Match a residual sign against the bank using optional static priors.

Static priors do not force a detection. They only apply bounded threshold scaling to the candidate heuristic they target.

pub fn len(&self) -> usize

Number of entries in the bank.

pub fn is_empty(&self) -> bool

Whether the bank is empty.

pub fn version(&self) -> &'static str

Bank version identifier.
