Enum MemoryBackendKind 

pub enum MemoryBackendKind {
    None,
    Sqlite,
    Postgres,
    Qdrant,
    Markdown,
    Lucid,
}

Per-agent memory backend selector.

Closed set; the schema is law. The enum mirrors the storage-instance outer keys under Config.storage.<kind>.<alias>: sqlite, postgres, qdrant, markdown, lucid, plus none for the no-storage case.

An agent’s backend is locked at agent creation and immutable on subsequent loads. Config::validate() enforces immutability against the persisted on-disk state.

Variants

None

No memory backend. Recall returns empty; stores are no-ops.

Sqlite

Embedded SQLite (crates/zeroclaw-memory/src/sqlite.rs). Default for new installs because every supported platform can run it without extra services.

Postgres

PostgreSQL with optional pgvector (crates/zeroclaw-memory/src/postgres.rs, feature memory-postgres).

Qdrant

Qdrant vector store (crates/zeroclaw-memory/src/qdrant.rs).

Markdown

Markdown files in the agent’s workspace (crates/zeroclaw-memory/src/markdown.rs).

Lucid

Hybrid local SQLite + external Lucid CLI (crates/zeroclaw-memory/src/lucid.rs).

Trait Implementations

impl Clone for MemoryBackendKind

fn clone(&self) -> MemoryBackendKind

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MemoryBackendKind

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for MemoryBackendKind

fn default() -> MemoryBackendKind

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for MemoryBackendKind

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl HasPropKind for MemoryBackendKind

const PROP_KIND: PropKind = PropKind::Enum

impl Hash for MemoryBackendKind

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl JsonSchema for MemoryBackendKind

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for MemoryBackendKind

fn eq(&self, other: &MemoryBackendKind) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for MemoryBackendKind

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for MemoryBackendKind
