Struct WasmDB 

pub struct WasmDB { /* private fields */ }

WebAssembly ReifyDB Engine

Provides an in-memory query engine that runs entirely in the browser. All data is stored in memory and lost when the page is closed.

Implementations

impl WasmDB

pub fn new() -> Result<WasmDB, JsValue>

Create a new in-memory ReifyDB engine

Example

import init, { WasmDB } from './pkg/reifydb_engine_wasm.js';

await init();
const db = new WasmDB();

pub fn query(&self, rql: &str) -> Result<JsValue, JsValue>

Execute a query and return results as JavaScript objects

Example

const results = await db.query(`
  FROM [{ name: "Alice", age: 30 }]
  FILTER age > 25
`);
console.log(results); // [{ name: "Alice", age: 30 }]

pub fn admin(&self, rql: &str) -> Result<JsValue, JsValue>

Execute an admin operation (DDL + DML + Query) and return results

Admin operations include CREATE, ALTER, INSERT, UPDATE, DELETE, etc.

Example

await db.admin("CREATE NAMESPACE demo");
await db.admin(`
  CREATE TABLE demo.users {
    id: int4,
    name: utf8
  }
`);

pub fn command(&self, rql: &str) -> Result<JsValue, JsValue>

Execute a command (DML) and return results

Commands include INSERT, UPDATE, DELETE, etc. For DDL operations (CREATE, ALTER), use admin() instead.

pub fn query_with_params( &self, rql: &str, params_js: JsValue, ) -> Result<JsValue, JsValue>

Execute query with JSON parameters

Example

const results = await db.queryWithParams(
  "FROM users FILTER age > $min_age",
  { min_age: 25 }
);

pub fn admin_with_params( &self, rql: &str, params_js: JsValue, ) -> Result<JsValue, JsValue>

Execute admin with JSON parameters

pub fn command_with_params( &self, rql: &str, params_js: JsValue, ) -> Result<JsValue, JsValue>

Execute command with JSON parameters

Trait Implementations

impl Default for WasmDB

fn default() -> Self

Returns the “default value” for a type.

impl Drop for WasmDB

fn drop(&mut self)

Executes the destructor for this type.

impl From<WasmDB> for JsValue

fn from(value: WasmDB) -> Self

Converts to this type from the input type.

impl FromWasmAbi for WasmDB

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 WasmDB

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 WasmDB

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<WasmDB>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for WasmDB

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 WasmDB

fn none() -> Self::Abi

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

impl RefFromWasmAbi for WasmDB

type Abi = u32

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<WasmDB>

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 WasmDB

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRefMut<WasmDB>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl TryFromJsValue for WasmDB

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 WasmDB

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

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

impl VectorIntoWasmAbi for WasmDB

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

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

impl WasmDescribe for WasmDB

fn describe()

impl WasmDescribeVector for WasmDB

fn describe_vector()

impl SupportsConstructor for WasmDB

impl SupportsInstanceProperty for WasmDB

impl SupportsStaticProperty for WasmDB
