Struct ywasm::YMapEvent

pub struct YMapEvent { /* private fields */ }

Event generated by YMap.observe method. Emitted during transaction commit phase.

Implementations

impl YMapEvent

pub fn target(&mut self) -> JsValue

Returns a current shared type instance, that current event changes refer to.

pub fn path(&self) -> JsValue

Returns an array of keys and indexes creating a path from root type down to current instance of shared type (accessible via target getter).

pub fn keys(&mut self) -> JsValue

Returns a list of key-value changes made over corresponding YMap collection within bounds of current transaction. These changes follow a format:

• { action: ‘add’|‘update’|‘delete’, oldValue: any|undefined, newValue: any|undefined }

Trait Implementations

impl From<YMapEvent> for JsValue

fn from(value: YMapEvent) -> Self

Converts to this type from the input type.

impl FromWasmAbi for YMapEvent

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 YMapEvent

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 OptionFromWasmAbi for YMapEvent

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 YMapEvent

fn none() -> Self::Abi

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

impl RefFromWasmAbi for YMapEvent

type Abi = u32

The wasm ABI type references to Self are recovered from.

type Anchor = Ref<'static, YMapEvent>

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 YMapEvent

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RefMut<'static, YMapEvent>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl WasmDescribe for YMapEvent
