Module prelude

A “prelude” for crates using the futures crate.

This prelude is similar to the standard library’s prelude in that you’ll almost always want to import its entire contents, but unlike the standard library’s prelude you’ll have to do so manually:

use futures::prelude::*;

The prelude may grow over time as additional items see ubiquitous use.

Modules

• task
  Task notification.

Enums

• Async
  Indicates whether a value is available, or if the current task has been scheduled for later wake-up instead.
• Never
  A type with no possible values.

Traits

• AsyncRead
  Read bytes asynchronously.
• AsyncReadExt
  An extension trait which adds utility methods to AsyncRead types.
• AsyncWrite
  Write bytes asynchronously.
• AsyncWriteExt
  An extension trait which adds utility methods to AsyncWrite types.
• Executor
  A task executor.
• Future
  A future represents an asychronous computation that may fail.
• FutureExt
  An extension trait for Futures that provides a variety of convenient combinator functions.
• IntoFuture
  Types that can be converted into a future.
• Sink
  A Sink is a value into which other values can be sent, asynchronously.
• SinkExt
  An extension trait for Sinks that provides a variety of convenient combinator functions.
• Stream
  A stream of values produced asynchronously.
• StreamExt
  An extension trait for Streams that provides a variety of convenient combinator functions.

Type Aliases
