Struct AlphaMemoryIndex 

pub struct AlphaMemoryIndex { /* private fields */ }

Alpha Memory with automatic indexing for O(1) fact lookups

Implementations

impl AlphaMemoryIndex

pub fn new() -> Self

Create new alpha memory index

pub fn insert(&mut self, fact: TypedFacts) -> usize

Insert fact and update indexes

pub fn filter(&self, field: &str, value: &FactValue) -> Vec<&TypedFacts>

Filter facts by field value Uses index if available (O(1)), otherwise falls back to linear scan (O(n))

pub fn filter_tracked( &mut self, field: &str, value: &FactValue, ) -> Vec<&TypedFacts>

Filter facts and update statistics (mutable version for tracking)

pub fn create_index(&mut self, field: String)

Create index on a field

pub fn drop_index(&mut self, field: &str)

Remove index from a field

pub fn get_all(&self) -> &[TypedFacts]

Get all facts

pub fn get(&self, idx: usize) -> Option<&TypedFacts>

Get fact by index

pub fn len(&self) -> usize

Get number of facts

pub fn is_empty(&self) -> bool

Check if empty

pub fn indexed_fields(&self) -> Vec<&String>

Get indexed fields

pub fn stats(&self) -> &IndexStats

Get statistics

pub fn auto_tune(&mut self)

Auto-detect which fields to index based on query patterns Indexes fields that are:

1. Frequently queried (>50 queries)
2. Not already indexed

pub fn clear(&mut self)

Clear all facts and indexes
