Struct AsyncReactor 

pub struct AsyncReactor<T>(pub T);

An adapter for Sinks that behaves as an asynchronous Reactor (requires async).

Example

use reducer::*;
use futures::channel::mpsc::channel;
use futures::executor::block_on_stream;
use std::thread;

let (tx, rx) = channel(0);
let mut reactor = AsyncReactor(tx);

thread::spawn(move || {
    reactor.react(&'1');
    reactor.react(&'1');
    reactor.react(&'2');
    reactor.react(&'3');
    reactor.react(&'5');
    reactor.react(&'8');
});

assert_eq!(block_on_stream(rx).collect::<String>(), "112358");

Trait Implementations

impl<T: Clone> Clone for AsyncReactor<T>

fn clone(&self) -> AsyncReactor<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for AsyncReactor<T>

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

Formats the value using the given formatter.

impl<T: Default> Default for AsyncReactor<T>

fn default() -> AsyncReactor<T>

Returns the “default value” for a type.

impl<T> Deref for AsyncReactor<T>

type Target = T

The resulting type after dereferencing.

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

Dereferences the value.

impl<T> DerefMut for AsyncReactor<T>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl<T> From<T> for AsyncReactor<T>

fn from(original: T) -> AsyncReactor<T>

Converts to this type from the input type.

impl<T: Hash> Hash for AsyncReactor<T>

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<T: PartialEq> PartialEq for AsyncReactor<T>

fn eq(&self, other: &AsyncReactor<T>) -> 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<S, T, E> Reactor<S> for AsyncReactor<T>

where S: ?Sized, Self: for<'s> Sink<&'s S, Error = E> + Unpin,

type Error = E

The reason why the state couldn’t be sent through the sink.

fn react(&mut self, state: &S) -> Result<(), Self::Error>

Sends an owned version of the state through the sink.

impl<S, T, O> Sink<&S> for AsyncReactor<T>

where S: ToOwned<Owned = O> + ?Sized, T: Sink<O>,

type Error = <T as Sink<O>>::Error

The type of value produced by the sink when an error occurs.

fn poll_ready( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Result<(), Self::Error>>

Attempts to prepare the Sink to receive a value.

fn start_send(self: Pin<&mut Self>, state: &S) -> Result<(), Self::Error>

Begin the process of sending a value to the sink. Each call to this function must be preceded by a successful call to poll_ready which returned Poll::Ready(Ok(())).

fn poll_flush( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Result<(), Self::Error>>

Flush any remaining output from this sink.

fn poll_close( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Result<(), Self::Error>>

Flush any remaining output and close this sink, if necessary.

impl<T: Copy> Copy for AsyncReactor<T>

impl<T: Eq> Eq for AsyncReactor<T>

impl<T> StructuralPartialEq for AsyncReactor<T>

impl<'pin, T> Unpin for AsyncReactor<T>

where PinnedFieldsOf<__AsyncReactor<'pin, T>>: Unpin,
