Struct Void

pub struct Void;

A zero-sized helper struct to simulate a JS-interoperable Callback with no input arguments.

let cb: Callback<Void, usize> = Callback::new(|Void| 5);

Trait Implementations

impl Clone for Void

fn clone(&self) -> Void

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Void

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

Formats the value using the given formatter.

impl Default for Void

fn default() -> Void

Returns the “default value” for a type.

impl From<Void> for JsValue

fn from(_: Void) -> Self

Converts to this type from the input type.

impl FromWasmAbi for Void

type Abi = <JsValue as FromWasmAbi>::Abi

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

unsafe fn from_abi(js: Self::Abi) -> Self

Recover a Self from Self::Abi.

impl Hash for Void

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl IntoWasmAbi for Void

type Abi = <JsValue as IntoWasmAbi>::Abi

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

fn into_abi(self) -> Self::Abi

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

impl PartialEq for Void

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
