Struct DiskSearchStrategy 

pub struct DiskSearchStrategy<'a, Data, ProviderFactory>
where
    Data: GraphDataType<VectorIdType = u32>,
    ProviderFactory: VertexProviderFactory<Data>,
{ /* private fields */ }

The search strategy for the disk provider. This is used to create the search accessor for use in search in quant space and post_process function to reorder with full precision vectors.

Why vertex_provider_factory and scratch_pool are here instead of DiskProvider

The DataProvider trait requires ’static bounds for multi-threaded async contexts, but vertex_provider_factory may have non-’static lifetime bounds (e.g., borrowing from local data structures). Moving these components to the search strategy allows DiskProvider to satisfy ’static constraints while enabling flexible per-search resource management.

Trait Implementations

impl<'this, Data, ProviderFactory> SearchStrategy<DiskProvider<Data>, [<Data as GraphDataType>::VectorDataType], (<DiskProvider<Data> as DataProvider>::InternalId, <Data as GraphDataType>::AssociatedDataType)> for DiskSearchStrategy<'this, Data, ProviderFactory>

where Data: GraphDataType<VectorIdType = u32>, ProviderFactory: VertexProviderFactory<Data>,

type QueryComputer = DiskQueryComputer

The computer used by the associated accessor.

type SearchAccessor<'a> = DiskAccessor<'a, Data, <ProviderFactory as VertexProviderFactory<Data>>::VertexProviderType>

The concrete type of the accessor that is used to access Self during the greedy graph search. The query will be provided to the accessor exactly once during search to construct the query computer.

type SearchAccessorError = ANNError

An error that can occur when getting a search_accessor.

type PostProcessor = RerankAndFilter<'this>

The associated SearchPostProcessor for the final results.

fn search_accessor<'a>( &'a self, provider: &'a DiskProvider<Data>, _context: &DefaultContext, ) -> Result<Self::SearchAccessor<'a>, Self::SearchAccessorError>

Construct and return the search accessor.

fn post_processor(&self) -> Self::PostProcessor

Construct the SearchPostProcess struct to post-process the results of search and store them into the output container.
