Implementations

impl TokenJaccard

pub fn new(threshold: f64, min_tokens: usize) -> Self

pub fn load_from(&self, records: &[DecisionRecord])

Load entries from cached decisions.

pub fn insert(&self, record: &DecisionRecord)

Add a single entry.

pub fn tokenize(input: &str) -> Vec<String>

Tokenize an input string: split on whitespace + punctuation, lowercase, deduplicate, sort.

pub fn jaccard_coefficient(a: &[String], b: &[String]) -> f64

Compute Jaccard coefficient between two sorted token slices.

pub fn invalidate_role(&self, role: &str)

Remove all entries for a specific role.

pub fn invalidate_all(&self)

Remove all entries.

Trait Implementations

impl CascadeTier for TokenJaccard

fn evaluate<'life0, 'life1, 'async_trait>( &'life0 self, input: &'life1 CascadeInput, ) -> Pin<Box<dyn Future<Output = Result<Option<DecisionRecord>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Evaluate this tier. Returns Some(record) if the tier can make a decision, None if it should fall through to the next tier.

fn tier(&self) -> DecisionTier

The tier identifier.

fn name(&self) -> &str

Human-readable name for this tier.
