Struct DejaDbOptions 

pub struct DejaDbOptions {
    pub entity_relations: HashSet<String>,
    pub index_text: bool,
    pub encryption_key: Option<[u8; 32]>,
}

Open options.

Fields

entity_relations: HashSet<String>

Relations whose objects are entities (get OSP reverse-index rows). Defaults to the OMS mg: entity-valued vocabulary.

index_text: bool

Populate the FTS text column (BM25 leg). Turso’s experimental FTS costs ~150ms per write txn on segment commits — voice/edge deployments set this false (structural + vector legs still serve recall; §6).

encryption_key: Option<[u8; 32]>

Encryption-at-rest key: 32 bytes → AES-256-GCM via Turso’s page cipher. None = plaintext. Host-supplied capability, never persisted in the file — a bare open() cannot supply it, so encrypted files must be opened with open_with/open_encrypted. Destroying the key destroys the memory (crypto-erasure). Covers the memory database (grains, indexes, op-log, WAL); the .blobs CAS sidecar is not yet encrypted.

Trait Implementations

impl Default for DejaDbOptions

fn default() -> Self

Returns the “default value” for a type.
