Extension trait for custom index types

Required Methods

fn index_type(&self) -> &str

Index type name (e.g., “hnsw”, “ivfflat”, “gin”)

fn insert(&mut self, key: &Value, pointer: TuplePointer) -> Result<(), String>

Insert a key-value pair

fn search(&self, key: &Value) -> Result<Vec<TuplePointer>, String>

Standard lookup for point queries

fn knn_search( &self, query: &Value, k: usize, ) -> Result<Vec<(TuplePointer, f64)>, String>

k-NN search for vector similarity (returns k nearest)

fn serialize(&self) -> Result<Vec<u8>, String>

Serialize index to bytes for persistence

fn deserialize(bytes: &[u8]) -> Result<Box<dyn IndexExtension>, String>

where Self: Sized,

Deserialize index from bytes
