Trait Implementations

impl<C, Output, Effect, H, HC, HandledEffect, NewOutput, NewEffect, I> Effectful for Handled<C, H, HC, HandledEffect, I> where
    C: Effectful<Output = Output, Effect = Effect>,
    H: FnMut(Event<Output, HandledEffect>) -> HC,
    HC: Effectful<Output = NewOutput, Effect = Either<Continue<NewOutput>, NewEffect>>,
    Effect: Subset<HandledEffect, I, Remainder = NewEffect>, 

type Output = NewOutput

The type of the final result

type Effect = NewEffect

The type of the effects this computation will produce

fn poll(self: Pin<&mut Self>, cx: &Context) -> Poll<Self::Output, Self::Effect>

Resume the computation to a final value, registering the current task for wakeup if a handler starts handling an effect performed by the task

fn handle<H, HC, Effect, I>(self, handler: H) -> Handled<Self, H, HC, Effect, I> where
    Self: Sized,
    HC: Effectful,
    H: FnMut(Event<Self::Output, Effect>) -> HC,
    Self::Effect: Subset<Effect, I>, 

Takes a value handler and an effect handler and creates an effectful computation with the effects handled

fn embed<Target, Indices>(self) -> EmbedEffect<Self, Target, Indices> where
    Self: Sized, 

Creates an effectful computation whose effect is a superset of that of this one

fn left<R>(self) -> Either<Self, R> where
    Self: Sized, 

Combine this and the other computation with the same signature

fn right<L>(self) -> Either<L, Self> where
    Self: Sized, 

Combine this and the other computation with the same signature

fn boxed<'a>(
    self
) -> Pin<Box<dyn Effectful<Output = Self::Output, Effect = Self::Effect> + 'a>> where
    Self: Sized + 'a, 

Create a boxed computation

fn output<T>(self) -> Self where
    Self: Effectful<Output = T> + Sized, 

fn effect<E>(self) -> Self where
    Self: Effectful<Effect = E> + Sized, 

Important traits for IntoFuture<C>

impl<C> Future for IntoFuture<C> where
    C: Effectful<Effect = !>,  type Output = C::Output;

fn into_future(self) -> IntoFuture<Self> where
    Self: Effectful<Effect = !> + Sized, 

fn block_on(self) -> Self::Output where
    Self: Sized + Effectful<Effect = !>, 

Run the computation to completion on the current thread

fn next_event(self) -> NextEvent<Self> where
    Self: Sized, 

Create a computation which polls this until the first event occures.

impl<C, H, HC, E, I> Debug for Handled<C, H, HC, E, I> where
    C: Debug,
    H: Debug,
    HC: Effectful + Debug,
    HC::Output: Debug, 

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

Formats the value using the given formatter.
