Trait RetrievalBackend 

pub trait RetrievalBackend: Send + Sync {
    // Required method
    fn search_one<'life0, 'life1, 'async_trait>(
        &'life0 self,
        sub_query: &'life1 str,
        limit: usize,
        min_score: f32,
    ) -> Pin<Box<dyn Future<Output = Result<Vec<KnowledgeMatch>>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait,
             'life1: 'async_trait;
}

Executes a single sub-query search against whatever backs actual retrieval (embedding + vector/graph search). Implemented by callers — this crate has no opinion on persistence or embedding models.

Required Methods

fn search_one<'life0, 'life1, 'async_trait>( &'life0 self, sub_query: &'life1 str, limit: usize, min_score: f32, ) -> Pin<Box<dyn Future<Output = Result<Vec<KnowledgeMatch>>> + Send + 'async_trait>>

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

Run one search for sub_query and return scored matches.

Dyn Compatibility

This trait is dyn compatible.

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