Struct VectorMemory 

pub struct VectorMemory { /* private fields */ }

Vector memory supporting similarity search, optionally persisted to a path.

Trait Implementations

impl Clone for VectorMemory

fn clone(&self) -> VectorMemory

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Component for VectorMemory

fn kind(&self) -> ComponentKind

Returns the kind of component this is.

fn name(&self) -> &Symbol

Returns the component’s name symbol.

fn capabilities(&self) -> &[CapabilityName]

Returns the capabilities this component requires or grants.

fn reflect(&self, cx: &mut Cx) -> Result<Expr>

Produces a self-describing expression for inspection of this component.

impl EvalSite for VectorMemory

fn site_kind(&self) -> &'static str

Returns a short label naming the kind of site.

fn address(&self) -> &ServerAddress

Returns the address this site answers at.

fn codecs(&self) -> &[Symbol]

Returns the codecs this site can decode and encode.

fn answer(&self, cx: &mut Cx, frame: ServerFrame) -> Result<ServerFrame>

Answers frame, returning the reply frame.

fn as_any(&self) -> &dyn Any

Returns the site as &dyn Any for downcasting.

fn answer_with_timeout( &self, cx: &mut Cx, frame: ServerFrame, _timeout: Option<Duration>, ) -> Result<ServerFrame, Error>

Answers frame with an optional deadline. Defaults to EvalSite::answer.

fn close_connection(&self, _cx: &mut Cx) -> Result<(), Error>

Closes any connection backing the site. Defaults to a no-op.

fn stream( &self, cx: &mut Cx, frame: ServerFrame, sink: &mut dyn StreamSink, ) -> Result<(), Error>

Streams the answer to frame into sink. The default path answers once and emits a single chunk followed by end.

fn as_eval_fabric(&self) -> Option<&dyn EvalFabric>

Returns this site as an EvalFabric when it backs one. Defaults to None.

impl MemoryBackend for VectorMemory

fn append(&self, cx: &mut Cx, msg: Value) -> Result<()>

Appends one message to the backend.

fn recent(&self, cx: &mut Cx, count: u32) -> Result<Vec<Value>>

Returns up to count most recent entries.

fn search(&self, cx: &mut Cx, query: Expr, k: u32) -> Result<Vec<Value>>

Returns up to k entries matching query.

fn snapshot(&self, _cx: &mut Cx) -> Result<Expr>

Captures the full backend state as an expression.

fn restore(&self, cx: &mut Cx, snap: Expr) -> Result<()>

Replaces the backend state from a prior snapshot.

impl Object for VectorMemory

fn display(&self, _cx: &mut Cx) -> Result<String>

Render the object as a human-readable display string.

fn as_any(&self) -> &dyn Any

Expose the object for Rust downcasting.

fn header(&self) -> &ObjectHeader

Identity and trust header for the object; defaults to the shared anonymous header.

fn op(&self, _key: &OpKey) -> Option<&dyn Op>

Resolve the operation registered under key, if any.

fn claims( &self, _cx: &mut Cx, _pattern: &ClaimPattern, _sink: &mut dyn ClaimSink, ) -> Result<(), Error>

Emit the object’s claims matching pattern into sink.

fn snapshot(&self, _cx: &mut Cx) -> Result<Option<Datum>, Error>

Optional content-addressable snapshot of the object’s state.

impl ObjectCompat for VectorMemory

fn class(&self, cx: &mut Cx) -> Result<ClassRef>

Class object this value belongs to; defaults to nil.

fn as_expr(&self, cx: &mut Cx) -> Result<Expr>

Expression form of the object; defaults to an opaque extension node.

fn as_table(&self, cx: &mut Cx) -> Result<Value>

Project the object into a table value; the default exposes its display.

fn as_callable(&self) -> Option<&dyn Callable>

Callable view, if the object can be invoked.

fn as_class(&self) -> Option<&dyn Class>

Class view, if the object is a class.

fn as_shape(&self) -> Option<&dyn Shape>

Shape view, if the object is a shape.

fn as_object_encoder(&self) -> Option<&dyn ObjectEncode>

Object-encoder view, if the object encodes other objects.

fn as_read_constructor(&self) -> Option<&dyn ReadConstructor>

Read-constructor view, if the object decodes data forms.

fn as_number_domain(&self) -> Option<&(dyn NumberDomain + 'static)>

Number-domain view, if the object is a number domain.

fn as_number_value(&self) -> Option<&dyn NumberValue>

Number-value view, if the object is a domain number.

fn as_eval_fabric(&self) -> Option<&dyn EvalFabric>

Eval-fabric view, if the object is a distributed eval surface.

fn as_stream(&self) -> Option<&dyn Stream>

Stream view, if the object is a stream.

fn as_sequence(&self) -> Option<&dyn Sequence>

Sequence view, if the object is a sequence.

fn as_thunk(&self) -> Option<&dyn Thunk>

Thunk view, if the object is a deferred computation.
