Struct VectorDB 

pub struct VectorDB { /* private fields */ }

Main VectorDB class for browser usage

Implementations

impl VectorDB

pub fn new( dimensions: usize, metric: Option<String>, use_hnsw: Option<bool>, ) -> Result<VectorDB, JsValue>

Create a new VectorDB instance

Arguments

• dimensions - Vector dimensions
• metric - Distance metric (“euclidean”, “cosine”, “dotproduct”, “manhattan”)
• use_hnsw - Whether to use HNSW index for faster search

pub fn insert( &self, vector: Float32Array, id: Option<String>, metadata: Option<JsValue>, ) -> Result<String, JsValue>

Insert a single vector

Arguments

• vector - Float32Array of vector data
• id - Optional ID (auto-generated if not provided)
• metadata - Optional metadata object

Returns

The vector ID

pub fn insert_batch(&self, entries: JsValue) -> Result<Vec<String>, JsValue>

Insert multiple vectors in a batch (more efficient)

Arguments

• entries - Array of VectorEntry objects

Returns

Array of vector IDs

pub fn search( &self, query: Float32Array, k: usize, filter: Option<JsValue>, ) -> Result<Vec<JsSearchResult>, JsValue>

Search for similar vectors

Arguments

• query - Query vector as Float32Array
• k - Number of results to return
• filter - Optional metadata filter object

Returns

Array of search results

pub fn delete(&self, id: &str) -> Result<bool, JsValue>

Delete a vector by ID

Arguments

• id - Vector ID to delete

Returns

True if deleted, false if not found

pub fn get(&self, id: &str) -> Result<Option<JsVectorEntry>, JsValue>

Get a vector by ID

Arguments

• id - Vector ID

Returns

VectorEntry or null if not found

pub fn len(&self) -> Result<usize, JsValue>

Get the number of vectors in the database

pub fn is_empty(&self) -> Result<bool, JsValue>

Check if the database is empty

pub fn dimensions(&self) -> usize

Get database dimensions

pub fn save_to_indexed_db(&self) -> Result<Promise, JsValue>

Save database to IndexedDB Returns a Promise that resolves when save is complete

pub fn load_from_indexed_db(db_name: String) -> Result<Promise, JsValue>

Load database from IndexedDB Returns a Promise that resolves with the VectorDB instance

Trait Implementations

impl From<VectorDB> for JsValue

fn from(value: VectorDB) -> Self

Converts to this type from the input type.

impl FromWasmAbi for VectorDB

type Abi = u32

The Wasm ABI type that this converts from when coming back out from the ABI boundary.

unsafe fn from_abi(js: u32) -> Self

Recover a Self from Self::Abi.

impl IntoWasmAbi for VectorDB

type Abi = u32

The Wasm ABI type that this converts into when crossing the ABI boundary.

fn into_abi(self) -> u32

Convert self into Self::Abi so that it can be sent across the wasm ABI boundary.

impl LongRefFromWasmAbi for VectorDB

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<VectorDB>

Same as RefFromWasmAbi::Anchor

unsafe fn long_ref_from_abi(js: Self::Abi) -> Self::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for VectorDB

fn is_none(abi: &Self::Abi) -> bool

Tests whether the argument is a “none” instance. If so it will be deserialized as None, and otherwise it will be passed to FromWasmAbi.

impl OptionIntoWasmAbi for VectorDB

fn none() -> Self::Abi

Returns an ABI instance indicating “none”, which JS will interpret as the None branch of this option.

impl RefFromWasmAbi for VectorDB

type Abi = u32

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<VectorDB>

The type that holds the reference to Self for the duration of the invocation of the function that has an &Self parameter. This is required to ensure that the lifetimes don’t persist beyond one function call, and so that they remain anonymous.

unsafe fn ref_from_abi(js: Self::Abi) -> Self::Anchor

Recover a Self::Anchor from Self::Abi.

impl RefMutFromWasmAbi for VectorDB

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRefMut<VectorDB>

Same as RefFromWasmAbi::Anchor

unsafe fn ref_mut_from_abi(js: Self::Abi) -> Self::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl TryFromJsValue for VectorDB

fn try_from_js_value(value: JsValue) -> Result<Self, JsValue>

Performs the conversion.

fn try_from_js_value_ref(value: &JsValue) -> Option<Self>

Performs the conversion.

impl VectorFromWasmAbi for VectorDB

type Abi = <Box<[JsValue]> as FromWasmAbi>::Abi

unsafe fn vector_from_abi(js: Self::Abi) -> Box<[VectorDB]>

impl VectorIntoWasmAbi for VectorDB

type Abi = <Box<[JsValue]> as IntoWasmAbi>::Abi

fn vector_into_abi(vector: Box<[VectorDB]>) -> Self::Abi
