Trait VectorIndexFactory 

pub trait VectorIndexFactory: Send + Sync {
    type Index: VectorIndex;

    // Required methods
    fn create(&self, dim: usize) -> Result<Self::Index>;
    fn load(&self, path: &Path) -> Result<Self::Index>;
}

Separates “create a fresh index” from “load existing index from disk.” The factory holds the configuration (HNSW M, efConstruction, etc.) that is otherwise duplicated between the two operations.

Required Associated Types

type Index: VectorIndex

Required Methods

fn create(&self, dim: usize) -> Result<Self::Index>

Create a new empty index with the given vector dimension.

fn load(&self, path: &Path) -> Result<Self::Index>

Load an existing index from disk. Validates internal invariants on load.

Dyn Compatibility

This trait is dyn compatible.

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