Struct cushy::widget::SharedCallback

pub struct SharedCallback<T = (), R = ()>(/* private fields */);

A Callback that can be cloned.

Only one thread can be invoking a shared callback at any given time.

Implementations

impl<T, R> SharedCallback<T, R>

pub fn new<F>(function: F) -> Self

where F: FnMut(T) -> R + Send + 'static,

Returns a new instance that calls function each time the callback is invoked.

pub fn invoke(&self, value: T) -> R

Invokes the wrapped function and returns the produced value.

Trait Implementations

impl Animate for SharedCallback

fn animate(&mut self, elapsed: Duration) -> ControlFlow<Duration>

Invokes the callback and consumes no animation time.

impl Animate for SharedCallback<Duration, ControlFlow<Duration>>

fn animate(&mut self, elapsed: Duration) -> ControlFlow<Duration>

Invokes this callback to implement a custom animation.

Returning ControlFlow::Continue consumes the entire elapsed duration. Returning ControlFlow::Break completes the animation and yields the provided duration to the next animation.

impl<T, R> Clone for SharedCallback<T, R>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T, R> Debug for SharedCallback<T, R>

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

Formats the value using the given formatter.

impl<T, R> From<Callback<T, R>> for SharedCallback<T, R>

fn from(callback: Callback<T, R>) -> Self

Converts to this type from the input type.

impl IntoAnimate for SharedCallback

fn into_animate(self) -> Self::Animate

Invokes this callback when the animation progresses. Consumes no animation time.

type Animate = SharedCallback

The running animation type.

fn to_animate(&self) -> Self::Animate

where Self: Clone,

Returns a clone of this change as a running animation.

fn and_then<Other: IntoAnimate>(self, other: Other) -> Chain<Self, Other>

Returns an combined animation that performs self and other in sequence.

fn cycle(self) -> Cycle<Self>

where Self: Clone,

Returns an animation that repeats self indefinitely.

fn repeat(self, times: usize) -> Cycle<Self>

where Self: Clone,

Returns an animation that repeats a number of times before completing.

fn on_complete<F>(self, on_complete: F) -> OnCompleteAnimation<Self>

where F: FnOnce() + Send + Sync + 'static,

Invokes on_complete after this animation finishes.

impl IntoAnimate for SharedCallback<Duration, ControlFlow<Duration>>

fn into_animate(self) -> Self::Animate

Invokes this callback to implement a custom animation.

Returning ControlFlow::Continue consumes the entire elapsed duration. Returning ControlFlow::Break completes the animation and yields the provided duration to the next animation.

type Animate = SharedCallback<Duration, ControlFlow<Duration>>

The running animation type.

fn to_animate(&self) -> Self::Animate

where Self: Clone,

Returns a clone of this change as a running animation.

fn and_then<Other: IntoAnimate>(self, other: Other) -> Chain<Self, Other>

Returns an combined animation that performs self and other in sequence.

fn cycle(self) -> Cycle<Self>

where Self: Clone,

Returns an animation that repeats self indefinitely.

fn repeat(self, times: usize) -> Cycle<Self>

where Self: Clone,

Returns an animation that repeats a number of times before completing.

fn on_complete<F>(self, on_complete: F) -> OnCompleteAnimation<Self>

where F: FnOnce() + Send + Sync + 'static,

Invokes on_complete after this animation finishes.

impl<T, R> PartialEq for SharedCallback<T, R>

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.
