Struct reducer::AsyncDispatcher

pub struct AsyncDispatcher<T>(pub T);

An adapter for [Sink]s that behaves as an asynchronous Dispatcher (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 dispatcher = AsyncDispatcher(tx);

thread::spawn(move || {
    dispatcher.dispatch(1);
    dispatcher.dispatch(1);
    dispatcher.dispatch(2);
    dispatcher.dispatch(3);
    dispatcher.dispatch(5);
    dispatcher.dispatch(8);
});

assert_eq!(block_on_stream(rx).collect::<Vec<u8>>(), [1, 1, 2, 3, 5, 8]);

Trait Implementations

impl<T: Clone> Clone for AsyncDispatcher<T>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for AsyncDispatcher<T>

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

Formats the value using the given formatter.

impl<T: Default> Default for AsyncDispatcher<T>

fn default() -> AsyncDispatcher<T>

Returns the “default value” for a type.

impl<T> Deref for AsyncDispatcher<T>

type Target = T

The resulting type after dereferencing.

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

Dereferences the value.

impl<T> DerefMut for AsyncDispatcher<T>

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

Mutably dereferences the value.

impl<A, T> Dispatcher<A> for AsyncDispatcher<T> where
    T: Sink<A> + Unpin, 

type Output = Result<(), T::Error>

Either confirmation that action has been dispatched through the sink or the reason why not.

fn dispatch(&mut self, action: A) -> Self::Output

Sends an action through the sink.

Once this call returns, the action may or may not have taken effect, but it’s guaranteed to eventually do, unless the sink is closed in between.

impl<T> From<T> for AsyncDispatcher<T>

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

Converts to this type from the input type.

impl<T: Hash> Hash for AsyncDispatcher<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, 

Feeds a slice of this type into the given Hasher.

impl<T: PartialEq> PartialEq<AsyncDispatcher<T>> for AsyncDispatcher<T>

fn eq(&self, other: &AsyncDispatcher<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &AsyncDispatcher<T>) -> bool

This method tests for !=.

impl<A, T> Sink<A> for AsyncDispatcher<T> where
    T: Sink<A>, 

type Error = T::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>, action: A) -> 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.
