# Enum futures::AsyncSink [−] [src]

    pub enum AsyncSink<T> {
        Ready,
        NotReady(T),
    }

The result of an asynchronous attempt to send a value to a sink.

## Variants

`Ready`

The `start_send` attempt succeeded, so the sending process has started; you must use `Sink::poll_complete` to drive the send to completion.

`NotReady(T)`

The `start_send` attempt failed due to the sink being full. The value being sent is returned, and the current `Task` will be automatically notified again once the sink has room.

## Methods

### `impl<T> AsyncSink<T>`
[src]

#### `pub fn map<F, U>(self, f: F) -> AsyncSink<U> where
F: FnOnce(T) -> U,`
[src]

Change the NotReady value of this `AsyncSink` with the closure provided

#### `pub fn is_ready(&self) -> bool`
[src]

Returns whether this is `AsyncSink::Ready`

#### `pub fn is_not_ready(&self) -> bool`
[src]

Returns whether this is `AsyncSink::NotReady`

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
