Struct CustomStrategy

pub struct CustomStrategy<Q> { /* private fields */ }

Implements the strategy pattern for vector similarity search, allowing retrieval backends to define custom query generation logic through closures.

Implementations

impl<Q: Send + Sync + 'static> CustomStrategy<Q>

pub fn from_query( query: impl Fn(&Query<Pending>) -> Result<Q> + Send + Sync + 'static, ) -> Self

Creates a new strategy with a synchronous query generator.

pub fn from_async_query<F>( query: impl Fn(&Query<Pending>) -> F + Send + Sync + 'static, ) -> Self

where F: Future<Output = Result<Q>> + Send + 'static,

Creates a new strategy with an asynchronous query generator.

pub async fn build_query(&self, query_node: &Query<Pending>) -> Result<Q>

Generates a query using either the sync or async generator. Returns error if no query generator is set.

Errors

Returns an error if:

• No query generator has been configured
• The configured query generator fails during query generation
