Trait Implementations§

Source§

impl From<JsTransaction> for JsValue

Source§

fn from(value: JsTransaction) -> Self

Converts to this type from the input type.
Source§

impl FromWasmAbi for JsTransaction

Source§

type Abi = u32

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

unsafe fn from_abi(js: u32) -> Self

Recover a Self from Self::Abi. Read more
Source§

impl IntoWasmAbi for JsTransaction

Source§

type Abi = u32

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

fn into_abi(self) -> u32

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

impl LongRefFromWasmAbi for JsTransaction

Source§

type Abi = u32

Same as RefFromWasmAbi::Abi
Source§

type Anchor = RcRef<JsTransaction>

Same as RefFromWasmAbi::Anchor
Source§

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

Same as RefFromWasmAbi::ref_from_abi
Source§

impl OptionFromWasmAbi for JsTransaction

Source§

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.
Source§

impl OptionIntoWasmAbi for JsTransaction

Source§

fn none() -> Self::Abi

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

impl RefFromWasmAbi for JsTransaction

Source§

type Abi = u32

The Wasm ABI type references to Self are recovered from.
Source§

type Anchor = RcRef<JsTransaction>

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.
Source§

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

Recover a Self::Anchor from Self::Abi. Read more
Source§

impl RefMutFromWasmAbi for JsTransaction

Source§
