Struct CallbackWithContext 

pub struct CallbackWithContext<F: ?Sized> { /* private fields */ }

This is a reusable callback type, useful in contexts where a callback must be received from the user which will later be invoked with specific arguments.

Implementations

impl CallbackWithContext<Function>

pub fn call( &self, arg: impl Deref<Target = JsValue>, ) -> Result<JsValue, JsValue>

impl<F: ?Sized> CallbackWithContext<F>

pub fn new( callback: impl Into<CallbackWithContext<F>>, ) -> CallbackWithContext<F>

Trait Implementations

impl<F: ?Sized> Clone for CallbackWithContext<F>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<F: ?Sized> Debug for CallbackWithContext<F>

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

Formats the value using the given formatter.

impl<A, R: Default> Default for CallbackWithContext<dyn Fn(A) -> R>

fn default() -> Self

Returns the “default value” for a type.

impl<F: ?Sized> Deref for CallbackWithContext<F>

type Target = F

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl From<&CallbackWithContext<Function>> for Function

fn from(callback_with_context: &CallbackWithContext<Function>) -> Self

Converts to this type from the input type.

impl From<CallbackWithContext<Function>> for Function

fn from(callback_with_context: CallbackWithContext<Function>) -> Self

Converts to this type from the input type.

impl<F: Sized> From<F> for CallbackWithContext<F>

fn from(callback: F) -> Self

Converts to this type from the input type.

impl<F: ?Sized> From<Rc<F>> for CallbackWithContext<F>

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

Converts to this type from the input type.

impl<F: ?Sized> Hash for CallbackWithContext<F>

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<F: ?Sized> Ord for CallbackWithContext<F>

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<F: ?Sized> PartialEq for CallbackWithContext<F>

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<F: ?Sized> PartialOrd for CallbackWithContext<F>

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.
