Trait Implementations

impl Clone for Constant[src]

fn clone(&self) -> Constant[src]

Returns a copy of the value. Read more

fn clone_from(&mut self, source: &Self)1.0.0[src]

Performs copy-assignment from source. Read more

impl Debug for Constant[src]

fn fmt(&self, f: &mut Formatter<'_>) -> Result[src]

Formats the value using the given formatter. Read more

impl From<Constant> for Constant[src]

fn from(original: Constant) -> Constant[src]

Performs the conversion.

impl FromWasmAbi for Constant[src]

type Abi = u32

The wasm ABI type that this converts from when coming back out from the ABI boundary. Read more

unsafe fn from_abi(js: u32) -> Self[src]

Recover a Self from Self::Abi. Read more

impl IntoWasmAbi for Constant[src]

type Abi = u32

The wasm ABI type that this converts into when crossing the ABI boundary. Read more

fn into_abi(self) -> u32[src]

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

impl OptionFromWasmAbi for Constant[src]

fn is_none(abi: &Self::Abi) -> bool[src]

Tests whether the argument is a “none” instance. If so it will be deserialized as None, and otherwise it will be passed to FromWasmAbi. Read more

impl OptionIntoWasmAbi for Constant[src]

fn none() -> Self::Abi[src]

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

impl PartialEq<Constant> for Constant[src]

fn eq(&self, other: &Constant) -> bool[src]

This method tests for self and other values to be equal, and is used by ==. Read more

fn ne(&self, other: &Constant) -> bool[src]

This method tests for !=.

impl RefFromWasmAbi for Constant[src]

type Abi = u32

The wasm ABI type references to Self are recovered from.

type Anchor = Ref<'static, Constant>

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. Read more

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

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

impl RefMutFromWasmAbi for Constant[src]

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RefMut<'static, Constant>
