Trait RecallStore 

pub trait RecallStore: FactStore {
    // Required methods
    fn query_filtered(
        &self,
        embedding: &[f32],
        k: usize,
        filter: &Metadata,
        offset: usize,
    ) -> Result<Vec<(u64, f32, String)>, MemoryError>;
    fn query_excluding(
        &self,
        embedding: &[f32],
        k: usize,
        exclude: &Metadata,
    ) -> Result<Vec<(u64, f32, String)>, MemoryError>;
}

Vector recall over stored facts — the surface every crate::service::MemoryService::recall/search call goes through. FactStore is a supertrait because these queries return the content of the facts they rank; a backend cannot rank what it cannot store.

Required Methods

fn query_filtered( &self, embedding: &[f32], k: usize, filter: &Metadata, offset: usize, ) -> Result<Vec<(u64, f32, String)>, MemoryError>

Vector search for up to k ids, narrowed to facts whose metadata exactly matches every key in filter.

Errors

Returns MemoryError if the query fails.

fn query_excluding( &self, embedding: &[f32], k: usize, exclude: &Metadata, ) -> Result<Vec<(u64, f32, String)>, MemoryError>

Vector search for up to k ids, dropping facts whose metadata matches every key in exclude.

Errors

Returns MemoryError if the query fails.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
