Struct BackendSet 

pub struct BackendSet {
    pub embedder: Option<Arc<dyn Embedder>>,
    pub index: Option<Arc<dyn IndexBackend + Send + Sync>>,
    pub vector: Option<Arc<dyn VectorBackend + Send + Sync>>,
}

Result of backend initialization with optional components.

All backends are wrapped in Arc for shared ownership across services.

Fields

embedder: Option<Arc<dyn Embedder>>

Embedder for generating vector embeddings.

index: Option<Arc<dyn IndexBackend + Send + Sync>>

Index backend for full-text search (SQLite FTS5).

vector: Option<Arc<dyn VectorBackend + Send + Sync>>

Vector backend for similarity search (usearch HNSW).

Implementations

impl BackendSet

pub fn is_complete(&self) -> bool

Returns true if all backends were successfully initialized.

pub fn has_embedder(&self) -> bool

Returns true if at least the embedder is available.

pub fn has_index(&self) -> bool

Returns true if full-text search is available.

pub fn has_vector(&self) -> bool

Returns true if vector similarity search is available.

Trait Implementations

impl Default for BackendSet

fn default() -> BackendSet

Returns the “default value” for a type.
