Struct WasmQueryEngine 

pub struct WasmQueryEngine { /* private fields */ }

Implementations

impl WasmQueryEngine

pub fn new() -> Self

pub fn register_table( &self, name: &str, ipc_bytes: &[u8], ) -> Result<usize, JsValue>

Register Arrow IPC stream bytes as a named table. Replaces any existing table with the same name. Returns the number of rows registered.

pub async fn execute_sql(&self, sql: &str) -> Result<Vec<u8>, JsValue>

Execute SQL, return Arrow IPC stream bytes.

pub async fn execute_and_register( &self, sql: &str, register_as: &str, ) -> Result<Vec<u8>, JsValue>

Execute SQL, register result as a named table, return Arrow IPC stream bytes.

pub fn deregister_table(&self, name: &str) -> Result<bool, JsValue>

Deregister a single named table. Returns true if the table existed.

pub fn reset(&self)

Deregister all tables.

Trait Implementations

impl Default for WasmQueryEngine

fn default() -> Self

Returns the “default value” for a type.

impl From<WasmQueryEngine> for JsValue

fn from(value: WasmQueryEngine) -> Self

Converts to this type from the input type.

impl FromWasmAbi for WasmQueryEngine

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 WasmQueryEngine

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 WasmQueryEngine

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<WasmQueryEngine>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for WasmQueryEngine

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 WasmQueryEngine

fn none() -> Self::Abi

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

impl RefFromWasmAbi for WasmQueryEngine

type Abi = u32

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<WasmQueryEngine>

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 WasmQueryEngine

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRefMut<WasmQueryEngine>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl TryFromJsValue for WasmQueryEngine

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 WasmQueryEngine

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

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

impl VectorIntoWasmAbi for WasmQueryEngine

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

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

impl WasmDescribe for WasmQueryEngine

fn describe()

impl WasmDescribeVector for WasmQueryEngine

fn describe_vector()

impl SupportsConstructor for WasmQueryEngine

impl SupportsInstanceProperty for WasmQueryEngine

impl SupportsStaticProperty for WasmQueryEngine
