Trait Implementations

impl Clone for City

fn clone(&self) -> City

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for City

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Eq for City

impl From<City> for JsValue

fn from(value: City) -> Self

Performs the conversion.

impl FromWasmAbi for City

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 City

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 City

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 City

fn none() -> Self::Abi

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

impl PartialEq<City> for City

fn eq(&self, other: &Self) -> bool

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

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl RefFromWasmAbi for City

type Abi = u32

The wasm ABI type references to Self are recovered from.

type Anchor = Ref<'static, City>

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 City

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RefMut<'static, City>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl WasmDescribe for City

fn describe()
