Struct InstantBackend 

pub struct InstantBackend { /* private fields */ }

Instant backend (spike): owned vectors + brute-force search (placeholder)

Note: This is a spike scaffold to validate owned save/load and determinism, not a performance implementation. It can be swapped with a real instant-distance index while keeping the ApproxIndex API intact.

Trait Implementations

impl ApproxIndex for InstantBackend

fn build(spans: Vec<Span>) -> Self

Build from fully-embedded spans (embedding must be present)

fn search(&self, query_embedding: &[f32], k: usize) -> Result<Vec<ScoredSpan>>

Search top-k results for given query embedding

fn save_to_disk(&self, dir: &Path) -> Result<()>

Save owned index to disk

fn load_from_disk(dir: &Path) -> Result<Option<Self>>

Load owned index from disk

fn spans(&self) -> &[Span]

Return referenced spans

impl<'de> Deserialize<'de> for InstantBackend

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for InstantBackend

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,
