Struct JsChangesStream 

pub struct JsChangesStream { /* private fields */ }

JavaScript-friendly changes stream.

This provides the changes() API that yields the complete result set whenever data changes. The callback receives the full current data, not incremental changes - perfect for React’s setState pattern.

Implementations

impl JsChangesStream

pub fn subscribe(&self, callback: Function) -> Function

Subscribes to the changes stream.

The callback receives the complete current result set as a JavaScript array. It is called immediately with the initial data, and again whenever data changes. Perfect for React: stream.subscribe(data => setUsers(data))

Returns an unsubscribe function.

pub fn get_result(&self) -> JsValue

Returns the current result.

pub fn get_result_binary(&self) -> BinaryResult

Returns the current result as a binary buffer for zero-copy access.

pub fn get_schema_layout(&self) -> SchemaLayout

Returns the schema layout for decoding binary results.

Trait Implementations

impl From<JsChangesStream> for JsValue

fn from(value: JsChangesStream) -> Self

Converts to this type from the input type.

impl FromWasmAbi for JsChangesStream

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 JsChangesStream

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 JsChangesStream

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<JsChangesStream>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for JsChangesStream

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 JsChangesStream

fn none() -> Self::Abi

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

impl RefFromWasmAbi for JsChangesStream

type Abi = u32

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<JsChangesStream>

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 JsChangesStream

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRefMut<JsChangesStream>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl TryFromJsValue for JsChangesStream

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 JsChangesStream

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

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

impl VectorIntoWasmAbi for JsChangesStream

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

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

impl WasmDescribe for JsChangesStream

fn describe()

impl WasmDescribeVector for JsChangesStream

fn describe_vector()

impl SupportsConstructor for JsChangesStream

impl SupportsInstanceProperty for JsChangesStream

impl SupportsStaticProperty for JsChangesStream
