Struct SearchExtension 

pub struct SearchExtension { /* private fields */ }

CommandExtension implementation that routes FT.* commands and the HSET interception path through a shared VectorRegistry and SuggestionRegistry.

Every cloneable handle to a SearchExtension references the same registries; embedders who want to inspect the live FT.* surface (admin paths, tests) can clone the registry handles out via SearchExtension::registry and SearchExtension::suggestions.

Implementations

impl SearchExtension

pub fn new(registry: Arc<VectorRegistry>) -> Self

Wrap an existing registry in a SearchExtension. The suggestion-dictionary registry is allocated fresh; callers that want to share it explicitly can use Self::with_suggestions.

pub fn with_suggestions( registry: Arc<VectorRegistry>, suggestions: Arc<SuggestionRegistry>, ) -> Self

Wrap both registries in a SearchExtension.

pub fn registry(&self) -> &Arc<VectorRegistry>

Borrow the wrapped vector-index registry.

pub fn suggestions(&self) -> &Arc<SuggestionRegistry>

Borrow the wrapped suggestion-dictionary registry.

Trait Implementations

impl Clone for SearchExtension

fn clone(&self) -> SearchExtension

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CommandExtension for SearchExtension

fn handles_msg_type(&self, ty: MsgType) -> bool

True when the parsed MsgType is one this extension wants to dispatch. The dispatcher only invokes Self::try_dispatch when this returns true.

fn try_dispatch(&self, args: &[&[u8]]) -> Option<Vec<u8>>

Try to dispatch a command. args is the parsed RESP argument vector starting with the command keyword (e.g. [b"FT.SEARCH", b"idx", ...]).

fn try_intercept_hset(&self, args: &[&[u8]]) -> HsetOutcome

Inspect an HSET argument list and, if it matches a registered prefix / shape, perform any side-effects the extension wants. args is [key, f1, v1, f2, v2, ...] (without the leading HSET keyword).

impl Debug for SearchExtension

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

Formats the value using the given formatter.

impl Default for SearchExtension

fn default() -> Self

Returns the “default value” for a type.
