pub fn rs_inner_owned(&self) -> Option<R>

impl<J: AsRef<Function>> Callback<dyn Fn(), J>

pub fn call_with_no_arg(&self)

If the function is a rust callback, the argument is supplied, otherwise the javascript function is called without any arguments.

impl<A, J: AsRef<Function>> Callback<dyn Fn(A), J>

pub fn call_with_rust_arg(&self, a: A)

If the function is a rust callback, the argument is supplied, otherwise the javascript function is called without any arguments.

impl<A, R: JsCast, J: AsRef<Function>> Callback<dyn Fn(A) -> R, J>

pub fn call_with_rust_arg_and_return(&self, a: A) -> R

If the function is a rust callback, the argument is supplied, otherwise the javascript function is called without any arguments.

Returns the result value

impl<A: Into<JsValue>, J: AsRef<Function>> Callback<dyn Fn(A), J>

pub fn call_with_js_arg(&self, a: A)

Calls either underlying callback with the argument supplied

impl<W: Into<JsValue>, A: IntoJsWrapper<Result = W>, J: AsRef<Function>> Callback<dyn Fn(A), J>

pub fn call_with_into_js_arg(&self, a: A)

Calls either underlying callback with the argument supplied

impl<A: AsRef<JsValue>, J: AsRef<Function>> Callback<dyn Fn(A), J>

pub fn call_with_as_js_arg(&self, a: A)

Calls either underlying callback with the argument supplied

impl<W: Into<JsValue>, A: IntoJsWrapper<Result = W>, R: JsCast, J: AsRef<Function>> Callback<dyn Fn(A) -> R, J>

pub fn call_with_into_js_arg_and_return(&self, a: A) -> R

Trait Implementations

impl<R: ?Sized, J: AsRef<Function>> Clone for Callback<R, J>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<R: ?Sized, J: AsRef<Function>> Debug for Callback<R, J>

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

Formats the value using the given formatter.

impl<R: Sized, J: AsRef<Function>> From<R> for Callback<R, J>

fn from(callback: R) -> Self

Converts to this type from the input type.

impl<R: ?Sized, J: AsRef<Function>> From<Rc<R>> for Callback<R, J>

fn from(callback: Rc<R>) -> Self

Converts to this type from the input type.

impl<R: ?Sized, J: AsRef<Function>> Hash for Callback<R, J>

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<R: ?Sized, J: AsRef<Function>> PartialEq for Callback<R, J>

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

impl<R: ?Sized, J: AsRef<Function>> PartialOrd for Callback<R, J>

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
