Configuration for engine construction.

Fields

raw_journal_path: Option<String>

episodic_path: Option<String>

semantic_path: Option<String>

procedural_path: Option<String>

emotional_path: Option<String>

working_capacity: usize

decay_params: DecayParams

recall_mode: RecallMode

index_path: Option<String>

Path for the Tantivy full-text search index directory.

vector_index_path: Option<String>

Path for the redb-backed vector index file.

background_decay_interval_secs: Option<u64>

If set, enables background decay at this interval (in seconds). None = disabled.

background_dream_interval_secs: Option<u64>

If set, enables background dream processing at this interval (in seconds). None = disabled.

hnsw_threshold: usize

Number of vectors at which to switch from brute-force to HNSW search. Default: 1000. Set to usize::MAX to always use brute-force.

llm_provider: Option<Arc<dyn LLMProvider>>

Optional LLM provider for auto-embedding, summarization, and relation extraction. When None, the engine operates without LLM capabilities (manual embeddings only).

Trait Implementations

impl Default for EngineConfig

fn default() -> Self

Returns the “default value” for a type.
